Well that, I had to research, because it goes against all that I knew - all metals are conductive.

All that I was able to find was that the chromium oxide, like very many metal oxides can be none conductive, or a semi-conductor. The chromium oxide appears on the surface of stainless steel and can make the surface none conductive, the underlying stainless steel remains conductive. As confirmed sometimes, by being unable to get a decent connection to the metal surface with a test meter. Stainless steel, depending on the type, has a conductivity between 3% and 15% of that of copper - so not a good conductor, but certainly a conductor.

The photo's in my post above were of my Tourer late 04 plate so some do have the flat/fanned ends ;)

The conductivity of quality stainless steel is lower than 0.000001% which is as good as rubber or plastic. As quality stainless steel has no carbon in it only silicon. Brings us back to the free electrons again. If there are no free electrons in the material then it can't conduct a current as it is the free electrons that allow the magic electricity to be conducted through it. I Remember reading an article half a century ago that when electricity was first discovered they thought it to be like water and would only flow down hill, until someone dropped the high end of the cable and it still worked.
I am going to invent a square wheel next year so when you stop the car will not run away from you it will just stay where you put it.
Only kidding!

Leaf stopper
 

I note that Aldi /Lidi have the rolls of gutter leaf stopper in again as it is coming towards September, I think you can also buy the from the pound shop, here is the link below worth doing before the onset of the autumn leaf dropping etc ;)

https://www.the75andztclub.co.uk/for...6&postcount=19

That would be useless for me, given the four pine trees a stonesthrow from my drive which drop their needles every autumn. I use open cell filter foam, which does the trick and keeps the pine needles out.

Ali.

Hi Ali.
I can see where you are coming from with the fact that those pine needles get into very place possible, to add another note this time of year anyone with a sunroof which have not done the sunroof drain mod can also be vigilant if take the risk at your own peril. ;)

Couldn't agree more.
Pine needles are all around here which is what gave me the idea of introducing my plenum guard.

In extreme cases more precautions need to be taken to stop the small debris going in the plenum area.

Cover the underside of the plastic plenum hatches with either fine netting or open cell sponge.

Sadly it as to be said the summer is over, and the wet seasons are now upon us, so lets not for get to check those plenums each weekend when you do your weekly oil and fluids checks I hope :eek: cheers Arctic

Hiya. Can anyone tell me how long it takes roughly for your plenum drain to collect standing water 2 inches up the pollen filter and the drain hole full of leaves that won't shift?
I had my local garage clean it out approximately six weeks ago because those leaves just would not budge... I also had to physically show them where the drain was…
I'm finding the same today.
I have managed to drain the water but not the leaves. Can the drain really get clogged up that badly in six weeks? Laura

Simple answer - YES it can.

A lot of water can run down the screen and be blown of the bonnet, much of which will end up collecting in the plenum, so the drains need to be checked frequently enough to ensure the water can drain away.

If the car is parked under trees, they need to be checked quite often. You can get an item from Jules, which helps considerably to prevent leaves and other large debris getting in there, or you can buy plastic gutter guard, which works similarly. Idea is to fix the open ends of the plenum, so they cannot get in, but yet allow water to flow through.

Rather asking an inexperienced garage to check them, check them yourself with a length of thin rod - you know for sure they are clear then.

Thanks Harry :) Laura

Hi Laura.
Yes it would be possible for the leaves to accumulate once again in that time scale, it depends on if you park where leave fall quite a lot, also if they cleaned out the plenum drain properly, did they cut the ends of a little about 12mm so the water can get out easier?

The easiest way to remove the leaves is with an hoover with the longest hose attached, also do the spy hole mod after so you do not have to keep removing the tray.

[QUOTE=Arctic;2541970]
Hi Arctic.

Going to try another garage that's been recommended and ask them to check the ends now you've mentioned it.
Will keep a closer eye on things now... Learning something new all the time :)

[QUOTE=HarryBowie;2559673][QUOTE=Arctic;2559453];)Hi Lara you can get the leaves out if you get the hover out.

Cleaned the plenums on my new acquisition yesterday, not being sure of it's history. Pouring water down and there was just a few drips from underneath the brake servo, so managed to scramble underneath and unblock this one whilst avoiding a torrent of water running up my arm - quite a bit of decayed leaf debris in there. The one under the ECU was ok. When I get a bit of time, and it's dry, I will take all the covers off and vacuum all the debris out.

I did check on my other car, but I don't tend to park under trees so these were all clear, although I did just have to clean the tube under the windscreen (the driver's side one they deleted in Project Drive) - at least the later tubes are less prone to blockages.

Checked the sunroof drains and i had drips from all four corners but I will check them properly.

I really hate this time of year. . . .

This is what greeted me this morning after a windy night.
The needles get into places you really wouldn't imagine, including behind the waist trim. :mad::mad:

Checked my plenums today along with all my other checks I do every Sunday ie lights fluids tyres etc, few photos below you can see how the rod comes out from under the car.

Remove the outer guard Fig 1
https://i.imgur.com/tEQqgPUl.jpg1

This gives you access to the plenum under tray Fig 2
https://i.imgur.com/n9lXr5Nl.jpg2

Which in turn gives you access to the spy hole rubber grommet Fig 3
https://i.imgur.com/AwKerZ0l.jpg3

Remove said rubber grommet Fig 4
https://i.imgur.com/CJWtq4Nl.jpg4

Insert the rod through the tray Fig 5
https://i.imgur.com/eYvYwYhl.jpg5

Now the rod as been inserted it should go through the plenum tube, if the spy hole mod as been correctly measured, move the rod up & down to clear any debris in the tube. Fig 6
https://i.imgur.com/fdd0PGGl.jpg6

Fully insert the rod and it should appear under the car and touch the ground as here in Fig 7

https://i.imgur.com/8jm9IEWl.jpg7

At the same do the tow outer tubes which are situated in each side of the inner wings, mine have mesh covering over them which have a little hole for the rod to fit through. Fig 8
https://i.imgur.com/ACqvtxHl.jpg8

Once again same procedure insert the rod into the tube Fig 9

When inserted in the tube move in and out, up & down Fig 10/11
https://i.imgur.com/Ec43lSEl.jpg10

https://i.imgur.com/xH0arzcl.jpg11

All your plenum tubes should now be clear of any debris and the water/rain will flow freely out through them Fig 12
https://i.imgur.com/iS3xp24l.jpg12

At the same time you can also check that the drain hole under each of your wipers is not bunged up with debris also Fig 13/14

It is worth doing these quick preventive measures each week through the winter period in my opinion. Arctic ;)

Thanks for the info and pictures

Hi Brian.
a pleasure glad they helped, it is worth checking this time of year also that there is no water trapped the plenum drain tube and it as frozen, because if there is it can take a bit of time for it to thaw out, in the mean time with snow which can melt it could fill up the plenum quite quick.

A kettle of hot or warm water poured into the plenum from the passenger side could help thaw the frozen plug out.

You can pour warm water down the drivers side skuttle panel netting
It will find it's way to both lower drains.

Flooded plenum caused this on my diesel causing car not to start

You'll need one of these kits to stop it happening again.

These leaf guards just allow water down into the plenum instead of all that debris you found ;)

Plenum drain tubes
 

I have cleaned this plenum drain & discovered that there is no tube fitted, Does anyone know if a replacement is available
The old codger

Hi Chris
Drop one of the traders a PM I am sure they could find you one, which one are you after the one below the ECU or one of the inner wing tubes Arctic

Thanks for the pictures showing how to clean out plenum. Took Rover & my wife out for a drive today, passenger side carpet soaking wet. Noticed recently loads of condensation in car and a noise coming from the blower fan when cornering as if a piece of paper was catching, now I know what it was. Watched Steve's video on U tube showing water pouring out when plenum was cleaned, well, video had nothing on the amount of water that flooded out of mine would not have believed that so much could collect! Son did the job for me. Plenum's last cleaned by garage in March last year, then Jules plenum guard fitted. This problem was caused by a broken piece of plastic, Tee shaped, jammed down the drain, initially only able to poke a very thin cane down one side to release water then saw the problem. Soaked up as much water as I can from carpet and now put de humidifier bag in foot well.
Obviously need to get spy hole modification done and regular checks.

Thanks Arctic.

Very common for the skuttle panel clips to break off and block one of the lower drains.


Sounds like garage didn't clear the drain under the servo.
Both lower drains must be cut off and kept clear.

Both upper drains (early cars) or single drain passenger side (later models) must be kept clear.

The spyhole mod only checks one drain.
We clear all drains on servicing or whenever owners cars are in our workshop for MOT etc

Hi Martin.
Happy that the thread helped you out, when you get timer see if you can get under the car and cut about 15mm off the plenum tubes you will find these high up on either side of the car, do not mistake the A/C drain pipes for them which are lower down and have a flap on them.

here are a couple of links for you and others members whom may want to follow cheers Arctic.

Thanks for all this info and pictures, I had only ever rodded out the drain tube at the side. Will have to have a look at this when I get the old girl out of hibernation in a couple of weeks for this years adventure.

Ice plug in plenum tube ?
 

Hi Guys quick heads up with the big freeze we have just had those that have not checked theirs plenums over the last week maybe do so now, with the thaw on it's way with rain make sure you do not have an ice plug in the plenum tube.

Here’s a funny thing – in nearly 8 years of ownership, I’ve never ever rodded it, though I do check it regularly for flooding. Thing is, it’s always bone dry.

Now it has flooded at some stage in the past, as the ECM had a tide mark on it, was misbehaving, and had to be replaced by @marinabrian. But the plenum was dry then too…

But it’s never been even slightly wet in the time I’ve had it. And during all that time, I’ve lived in the countryside, with endless leaves, moths etc everywhere :shrug:

Quick heads up we are coming out of a long cold and wet winter, into a wet lots of rain spring :eek: nothing new for us in our wonderful land of GB.

Even if you have a leaf catcher fitted, it is always best to check your plenums at least once a week maybe do it when you check your cars fluid levels, tyre pressures, lights etc every weekend which what I hope most members do better safe a than sorry, happy motoring guys & gals.

Hi, I am a new 75 owner and only just found this forum. Thank you for sharing this info. My 75 ran perfectly for the first 4 weeks I owned it and then started to have issues, shutting down the engine randomly, door open warning light coming up whilst driving but going away whilst cornering etc.

After reading this thread I checked my plenum and discovered about an inch of water in it. We in rural South Australia haven't had any rain for months so I can only guess it is from washing the car each weekend.

Now I have cleared the drain and released the water some problems have gone away whilst others are less frequent.

Cheers

plenum help cheshire
 

Hi is there any one around the Cheshire area who will A replace pollen filter B make sure my drain tubes are clear willing to see some right for the help :} Oh its diesel 75 2004

Hi Ronald.
Did you find anyone to help you, if not maybe this little bump will see someone come forward for you cheers Arctic. ;)

wet carpets...
 

Although I've owned a Rover 75 for almost 3 years I've never touched the plenums (learning all the time...) and I've never had a problem with that part of the car - I think. No soggy carpets ever.

Now I have a MG ZT V6 2004 facelift model (for the last few weeks) and, as we all know, we've had lots of rain. Now I have lots of water in the driver's footwell and under the seat in the sort of recess there - and in the rear offside passenger footwell. I mop it up and it returns.

I do know I have a misty wet windscreen on the inside sometimes...

I've just inspected the plenum covers (as I think they are!!) on the left and right of the car - both bone dry and when I used a makeshift rodding device in the two holes near the gas struts on the left and right I felt no obstruction and it appears all dry. So... am I looking in the right place and maybe there is more to the plenum inspection than this? I know I sound really naive!!!

Also - is this a possible factor? I've just had a new clutch last week and it kind of looks to me like the water is coming in from the general direction of the gearbox (which came out).

Hello - i think you will more likely get a response if you post in the general Technical section below - folk will not generally look in the sticky.;)

You have been very lucky so far then...


You need to remove those covers and check for water below them. The drains are at the very bottom and the plenums are the space between the two bulkheads. They potentially can hold several gallons of water, if the drains are not cleared and checked regularly.

I'm a novice so advance apologies.

This is the plenum cover on the n/s, yes?

There's one drain hole at the extreme right of the cover (partially visible) like a rubber bung but more like a short piece of tubing that fits in a hole. It is all dry in there. Everywhere that I can see save for my poor carpets.

Or do I need to remove the "tray" that is under the cover in the picture?

If I am better off posting elsewhere for advice then I will, of course.

No - they are drains, but they only allow drainage of some of the water, higher up.



You cannot see the drains, they are too deep below. One O/S is buried under the brake unit, which itself is under a clip on plastic cover. The N/S is visible, but only after the cover is removed and peering past the heater pollen filter - that will be wrecked as well.



Both become completely blocked by leaves and debris needing to be checked and cleared regularly, to prevent problems. Even more of a problem for a diesel, because the engine ECU is in the N/S plenum. They especially need to be frequently checked at this time of year, when all the leaves are falling..

Hi Michael.
Hopefully you will have read post one of this thread,
https://www.the75andztclub.co.uk/for...89&postcount=1

Extra to that you can also check the plenum tubes from under the car as in the link below.

https://www.the75andztclub.co.uk/for...33&postcount=9

https://the75andztclub.co.uk/forum/s...ad.php?t=84865

Also do you have a sunroof if so then check out this thread below.
https://www.the75andztclub.co.uk/for...d.php?t=118622

Put some finer mesh or air filter fabric on the skuttle covers as well as the Jules plenum guard.
And debris won't get in the bulk head:cool:

Another good tip is visit a garden centre which as some sort of aquatic section attached to it.

Most will sell the round mesh foam which you can cut in half and insert into each wing channel where the drainage hole is, this will then stop any debris blocking those drainage holes up, also if you do not have a Jules plenum guard it will stop debris from entering the plenum on the drivers side.

My first rodding completed!

I had lots of unwelcome water in the driver's footwell and in the rear footwell too (started on Friday evening when we had the first of the weekend's heavy rain). Not good. Anyway, I invested in a 15mm plumber's pipe bender spring from B&Q and added a piece of 15mm plastic tubing to that with cord. I managed to remove the tray beneath the grille thing which unclips and sure enough there was standing water in the chamber. I rodded all the way through to the underside and water came running out and continued for a couple of minutes, with bits of leaf matter on the drive too. I rodded several times to try and clear the rubbish as best I could and I shall install a spy-hole next to save the hassle of disassembly (I struggled a bit to replace the tray at first and one of the two clips on the grille has broken due to age).

I'm pleased with myself as I'm pretty hopeless with most car maintenance issues!

PS Do you think the pollen filter is knackered after being soaked? Is that easy enough to replace?

Hi Michael.
Excellent work carried out you now need to make sure you dry out under the carpet other wise you will have a terrible smell coming from it, also the foam hold a lot of water, the water you saw in the foot wells was only because the foam could not soak up any more, or you may have just been unlucky and it got flooded through the pollen filter vent.

Which brings me on to the pollen filter yes it will need changing as it is now ruined link below on how to fit them, even though this how to is for the diesel car they are the same over the range, easy on petrol engines cheers Arctic.

https://www.the75andztclub.co.uk/for...d.php?t=170300

Thanks Arctic

Yes pollen filter and the spy-hole mod at the weekend all being well.

Quick question on soggy carpets... I guess I don't want to underestimate the amount of water in them and the foam... Just driven the car post rodding and the carpets are wet again. I'm guessing that the movement of the car dislodges the water and brings it to the surface (which at least I can mop up).

I'll have to take more steps though to eliminate the water but I don't much want to remove the carpets..

Hi Michael.
I think I may have asked already do you have a sunroof in your car? if so that could be the reason for most of the water.

IF not and enough as been allowed to get through the pollen vent, then this is what could well be under your carpets, link below.

Thanks again Arctic

No I don't have a sunroof and in my (original) naive way I thought when it was raining heavily last Friday and Saturday (and the lanes near me were really wet with standing water) water might have been coming in through a gap in the door seal or from underneath but I know better now...

I think I'll have to seek some help to rid the car of excess water. What happens is I towel up the water from the carpet but when I drive the car again I have a lot of water reappearing on the carpets front and rear (and under the driver's seat). Thankfully only on the right hand side.

Worth checking that the rubber seal for the steering shaft where it goes through the body is correctly fitted.

You say rear carpets too.---Is there any water in the boot ??

Water leaks in there can show up on the rear carpets if the car is now and then parked nose down hill.----:eek::eek::eek:

Couldn't directly find this in this topic, so I thought this could be a good place to share it:

The hose for the clutch goes through the scuttle panel, into the area where also the brake cylinder is (right underneath it). If the grommet is worn/damaged, or you replaced it with the copper tubing from the Tazu clutch cylinder, chances are very good that it is leaking through there. You wont notice anything, because the water will flow down behind the dashboard, right behind the carpet into the footwell.
Only way I found it was by literally putting my hand underneath the carpet and feeling if it was moist. It was soaking moist....

Plenum check if freezing weather
 

Hi Members /owners keep an eye on the plenums with this rain, then the freezing weather, it only need the plenum drain hole to be a little blocked it will then hold water, in turn it will freeze and create a solid ice plug, which then can take a while to thaw even if it rains which then can flood the plenum, so better to safe than sorry do a check and rod the plenum to make sure ;)

Torrential rain as now stopped here in the midlands, so a quick double check of the plenums through the spy hold mod, all looks to be in good order, if you have or had the heavy rain over the last few days then always keep in mind it only takes a few minutes to check those plenums, better to be safe than sorry.

Just checked mine today, all dry and the drain was clear but did get out a handful of dry leaves. So it was worth the few minuets it took.:}

Fit some sponge or better still one of our Plenum leaf guards kits.
Stops leaves and debris getting in there in the 1st place then you can sleep at night 😎

http://www.the75andztclub.co.uk/foru...ad.php?t=68328

As above I fitted some fish tank filter works a treat, I fitted them at the same time as refurbishing the scuttle panel & the plenum top guard covers, easy to remove to rod the drains and easy to wash out with a water hose if you so wished ;)

Nothing surprising about it being dry when you check it - the thing is if the water cannot get awy fast enough, due to a partial blockage, then it will flood. Yet when you go out and check for flooding on a dry day, it can be all dry.



You check them to make sure the water can get away without any restriction allowing it to build up.

All depends where these cars live.

Some (and we've worked on 1000's) don't have any debris in from 1 year to the next.

Depends if you live near trees basically 😎

Copperleaf had the Jules plenum guard fitted around 2 years ago and yet still get problems, because my parking area is surrounded by pine trees. The needles get everywhere and short of moving house the only thing to do is keep on rodding!

Martin.
Even more reason to cut off those drain tubes by 15mm also at the next Nano ask me about some fish tank filter.

You need to fit the skuttle panels with a filter material.
Stops all the debris 100%

Hello & good morning to all owners & members, just a quick reminder while we have this deluge of none stop rain check those plenums, as any tiny form of blockage/debris will stop this amount of water getting away quickly, we don't want the ECM going for a swim that's for frogs & fishes :D

Just to echo what Arctic keeps saying about checking plenums, whilst fitting the spy hole modification this evening during a break in the heavy rain I thought it a good idea to check the cabin filter of the newly acquired diesel 75.
One of the filters has been in the old car for about 3k miles and the other appears to have done 14 years. Answers on a postcard please. https://uploads.tapatalk-cdn.com/201...6663e2641a.jpg

Yep many garages charge for a service but don't change the filter.

To me the pollen filter is more important than the oil filter.
It's what you breath into your lungs !!!!!!!

All sorts of spores get in there and always a risk of legionnaires disease if filter stays wet.

Agree the shields do their job in the majority of parking areas but in leafy areas more protection is required as Arctic describes above.

We did originally design some finer filters to go over the standard 2 netted covers already there (they are simply not fine enough)
Most other makes have much finer cabin intake grills and don't suffer the ingress of forest matter !!

We never got round to putting them into production
Daft really but not enough hours in the day here.

What we suggest is sticking more fish tank filter material to the plenum cover grills to add even further protection ;)

soi put the tip of my power washer on tip of thr plenum and blasted them out .


if this is not enough can some of ye let me know.
i taught it was a good idea but if im fooling my self:eek::eek:
thank you.


Rob

Not really a good idea to splash high pressure water around that area and what would happen if the drains were block and the plenums filled up?

Almost any thin, flexible rod will do to clear the drains out of debris. The end of the rod should appear below the car, pushing any debris out with it. Then you can rinse them out with a little low pressure water from a hose.

They need to be checked frequently, especially if there are falling leaves, or if the car is parked under/near trees. You can buy 'gutter guards' for not a lot, from Jules, which will help prevent leaves getting in.

You are bang on with the above these are fitted FOC at our Nano meets, you can purchase a round piece from any garden/fish pond outlet for £0.50p cut it in half and you have enough for both side inner top wings. ;)

I've kept my photos in my computer and also on a number of memory sticks. It would be catastrophic to lose the lot.

The work you've done ( and there's so much of it ) NEEDS those pictures.

I hope you find time to re-instate some of the most important ones.--:D

If anyone still have images on Photobucket they will find that you are only able to download one at a time. :duh:
I suppose that they want to make any transfer to another host very difficult. ;)

I went to the Google store and got the "Photobucket Album Downloader (Unlimit)" as a Chrome extension.
A bargain at £1.29 for all of the trouble it saves

:smilie_re: https://chrome.google.com/webstore/d...pkeopelc?hl=en

I have found it to be brilliant and it takes about 30 secs to download 100 photos.
I retrieved 961 images in minutes, which are now safely on my own hard drive.

Luckily in 2007 I chose Picasa run by Google and even when they stopped supporting it they transferred everything over to their Photos App.

So all my photos and hyperlinks still work .......unless anyone tells me otherwise ;)

Just curious Jules..--Does that mean you have all your eggs in one basket, so to speak ??

If so, I hope that basket doesn't have a shelf life.---:eek::eek::eek:

Nope

Got backups on old PC's and duplicates on USB sticks etc..

Never rely solely with online data.
Always keep copies yourself especially if it's your livelihood ;)

Costs me 5.99 a year, but it gives me 10gb server room, with a domainname and several CMS to choose from. Just picked a photo-upload cms (coppermine), and I've got my own private image hosting party. Bandwidth has never been a problem.

When I was in IT before retirement, I constantly astonished me how people just trusted computers/websites/whatever with stuff that REALLY mattered. One senior manager in the insurance company I worked for kept all her stuff on her ancient Compaq P166 (well… that was a while ago…) despite my nagging her to put it on the server, which was backed up every night.

She wouldn't, because she felt that other people might get access to her stuff – I didn’t think it advisable to let her know I could access the data on her computer any time I wanted anyway, if she didn’t encrypt folders etc.

The day came when her hard disk crashed, and she asked me to get her stuff back – it was a hard crash, so I couldn’t, and she went mental, telling me she had lost two years’ budget work, like it was my fault.

Anyway, the moral with data (pics etc) is: if it matters, it MUST be in (at least) two places, eg PC and USB stick, or PC and cloud. That way, you lose one, you still have the other ;)

All my photo's are on my PC 1TB hard drive, backed up on an external 1TB drive, then backed up again on another 1TB external drive.

Also they were on three hosting site Photo Bucket, inypic, and now Imgur. so I do not have the worry of losing the content of my photo's its the out side third party hosting that is the trouble as we now know PB are just a nightmare.

I suppose all outside hosting companies will go the same way, it is all about profit for them yet they are not getting my custom so they must be losing out somewhere along the line. :shrug:

I have to be careful as I do not want to turn this thread into another PB debatable topic when I already have one running.

So many threads on here go off track it's unreal, and you end up trudging through pages of posts that have nowt to do with the matter subject.

As I say I have all the relevant/applicable photo's to my threads but it is the man power in time I do not have to sort out ever thread, so I will do them as and when I can sorry guys :cry:

Respect Steve :eek:

Not many like you though...

Arctic it might be better to host your own website for stuff like this.;)

HI Jules.
Any suggestions please for a good website and what is the cost for doing something like that ? do you know, you can PM if you like or add here :} thank you Arctic.

Your own broadband provider usually have some free webspace.

Mine is Plusnet but most have the facility ;)

Video Plenums
 

Don't forget those plenums as we have had quite a lot of rain over the last week or so, also check out the video below.

https://youtu.be/JwAj8r36Uno

Check out this one too. :D


https://youtu.be/9Hw2SMBPU48

Please can someone explain why this post is still here since the photos are no longer
 

Please can someone explain why this post is still here since the photos that are vital are no longer available. I really need to know how to do this and I can't because the photos are gone

It is because "Tiny Pics" was taken over by the Photobucket crooks and they have deleted the images from the server.

Nothing to do with the content on here. ;)

Hi John.
Yes because I intend to replace the photo's once I have a chance to do so, photo bucket took over (Tinypic) which I used for all my how to's so I have a mammoth task before to re-instate all the photo's which I am doing one how to at a time when I can.

In the mean time lets hope this helps you ;)

https://youtu.be/9Hw2SMBPU48

Photo's now replaced to a fashion, will correct 100% over time but seeing we are having a deluge of rain at the moment, I have replaced most of the originals I am sure we all get the drift by now :}

Plenum revisit check
 

Today I revisited the plenum check, I did this because of the theft of the photo's from the original thread by PB via (Tinypic) whom they closed down when they purchased the site.


Therefore below is the revised version.

Tools I used for the plenum check. fig 1

https://i.imgur.com/KTTbmjOl.jpg42

Make sure the rod exits the plenum under the car fig 43
https://i.imgur.com/zTBQ8jFl.jpg43

After you have rodded all the debris out & cleaned the plenum floor you can replace the ECM, note the two guides on the rear of the case fig 44
https://i.imgur.com/XRkYBTUl.jpg44

The guides will match up to and slide into the bracket on the fire wall inside the plenum fig 45
https://i.imgur.com/0VAomv8l.jpg45

Make sure the ECM is seated fully down on the bracket fig 46
https://i.imgur.com/jg5XALul.jpg46

https://i.imgur.com/jMCmOFIl.jpg72

There is another lower plenum tube under the servo this is only reachable and serviced from under the car, except for the 1.8 engine which you are able to reach from in the engine bay.

Hopefully this helps new & old members and gives a full how to of the plenum clearance after the PB (Tinypic) debarcle cheers Arctic.

Inner wing drain tubes
 

As we know we also have two inner wing drain tubes on our cars NS & OS, these can and will get blocked also if not serviced by rodding or protected by some sponge.

The inner drain tube fig 1
https://i.imgur.com/PG2UtTel.jpg1

Use a rod to clear any debris in the tube. fig 2
https://i.imgur.com/eUXyT3Vl.jpg2

Push the rod in & out a few times making sure it go's in as far as possible.
https://i.imgur.com/rfebtzcl.jpg3

The ideal thing to do is remove the tube using a pair of long nosed pliers. fig 4/5/6
https://i.imgur.com/D4yicaXl.jpg4

https://i.imgur.com/Lr1W2pPl.jpg6

Once removed if the drain tube as any flaps cut them off.
https://i.imgur.com/JVPJxZOl.jpg7

Mine did not have any flap so was ok.
https://i.imgur.com/veH693bl.jpg8

Clean inside the inner wing with a rag fig 9

Push the tube fully home making sure it's sealed all round. fig 12/13
https://i.imgur.com/bKCKVQtl.jpg12

https://i.imgur.com/HYybpIHl.jpg13

With the drain tube flap cut off and inner wing area cleaned, add some fish tank filter to stop future debris. fig 14
https://i.imgur.com/lMH5T2il.jpg14

You need to filters one small and one longer fit the small one first. fig 15
https://i.imgur.com/9mvJAIIl.jpg15

Fit longer over the drain tube it's self fig 16/17
https://i.imgur.com/7aV9vIwl.jpg16

https://i.imgur.com/xrWtJnPl.jpg17

Do both OS & NS inner wings the same fig 18/19
https://i.imgur.com/fgfVKnNl.jpg18

https://i.imgur.com/APWYKBSl.jpg19

These are what the earlier type inner wing drain tubes look like before the face lift. fig 20

https://i.imgur.com/Bji0iUll.jpg25

If you do not have one on the NS wing area. then add one from a scrap car or get in touch with one of the traders (Mickyboy) i am sure if he as any he would supply for about £5 a worth while mod i think.

Check your plenums
 

If this is not a good reason to check your plenums I don't know what is, hopefully we managed to save the ECU only time will tell, it could well have got damp inside, car is running ok at the moment.

Fingers crossed he may not have to search out the Guru ECU men, don't leave the plenums to long in this weather more rain on the way according to the news.

Hi Members just a quick reminder about checking plenum, while we have all this rain it is best to check on a regular basis even if you have any sort of plenum guard.

Debris can & will still get into the plenum and build up which can block the tube, always better safe than sorry for the five minutes it take to check;)

Most importantly make sure that BOTH flat ended drain tubes underneath (above the steering rods) have been cut off.

The plenum leaf guard won't be as effective unless the final part of the mod has been carried out

75 drain tubes.
 

Hi. Just completed this check. All dry however dug out half a forest of leaves. Changed the filter whilst i was in there. Thanks to you guys for the advice, saved me a small fortune if got flooded. nice one. Tony 2003 75.

Yes - you have to vigilant with a Diesel as your ECU is not sealed nor waterproofed - unlike the MGR Petrol ECU's which are sealed and waterproofed - always wondered why thy did not seal them all. :shrug:

Possible ECU woes
 

Hello everyone.

prior to purchasing my 2003 diesel ZT last November I had found this forum whilst trying to educate myself about potential problems to look out for.

Having learned about the plenum issue I made it a point to check my drains with every wash. I would pour some water down the side drains and feel confident as I watched it all came out from under the car. Little did I know how naive I was being as I thought that this was what was being referred to and never checked the middle drain, under the ECU.

A few days ago my car lost power during a drive. After coasting to a safe parking spot, I tried restarting the car. Turning the key would crank the starter confidently but alas the car would not start. Had I not refueled earlier on I would have suspected that I ran out of diesel.

I noticed that I no longer heard the whine of the diesel pump when turning the ignition on. Theorising that it might be an electrical problem, I fiddled around with the fuses next to the battery, and tried turning the key again. To my surprise, the car started!

Alas, the happiness provided by my newfound electrical genius was short lived as the car turned off again within a few seconds. Another fiddle with the fuses let me start it up again, only to have it turn off once more after roughly the same amount of time. No amount of further prodding to the fuses and relays led to the car starting again, so I had to have it towed to the garage, defeated and disheartened.

I'll try to relay the troubleshooting steps that my mechanic described as well as I can:

He first tested the in-tank fuel pump. Supplying a direct charge made it turn however no fuel was reaching the engine bay before the high pressure pump. It may be of importance to mention that (I believe that) he noticed that when the ignition was off the fuel would arrive into the engine bay, but with the ignition, it wouldn't.

Computer diagnostics apparently gave nonsensical error messages consisting of a string of numbers rather than the usual letter followed by a number.

Upon accessing the ECU box he saw that there was water beneath it. A corner of the ECU box shows a water mark (diagonal lines on lower left corner):
https://i.ibb.co/rd33Br7/IMG-20200409-152026.jpg

The ECU itself looks like this (doesn't look bad):
https://i.ibb.co/2nMYCxt/IMG-20200409-152037.jpg


Close-ups of lower-left corner:
https://i.ibb.co/CBSyYgM/IMG-20200409-152046.jpg


https://i.ibb.co/kBzLNR2/closeup.jpg



There seems to be some mineral build-up along some of the traces. To my beginner electronics-hobbyist eyes it looks like the only components in this corner are resistors, diodes and what seem like transistors. Would these have been damaged upon contact with water, or would shorting these have caused damage further up-field?

Would this explain the fuel pump issue or could it be caused by something else? What about the strange error messages? Have I fried my ECU? Should I try cleaning with denatured alcohol?

Thanks to this forum I already repaired the leaking boot, solved a coolant leak issue that turned out to be broken O-rings, and I also replaced 3 rusted door trim panels with replacements from Rimmer Bros.


Losing use of the car to this is bumming me out.

Any advice would be very much appreciated.

Cheers

HI Ian.
You could try cleaning that area with some switch cleaner, and dry it out. but I think if it did work it would only be for a while.

Personally I would drop one or both of these guys a PM they should be able to help you out.

Hi Arctic,


thanks for the quick reply.
I'll repost.

Or you could PM ( private message. ) the two guys mentioned above.

As said, the tech section is where you need to be.

Good luck with it and get that spy hole drilled.---:D:D:D

Check Those Plenums
 

I know you may get fed up that i keep banging on about check those plenums, but with all the rain we are having it only takes 5 minutes ;)

Hi Artic,
Are the pictures still on the forum showing the measurements required to cut the ‘spy’ hole in the Plastic panel? It would appear the hosting company has deleted them☹️

97mm iirc

It was appreciated then Artics post came up!

Irritating isn't it sometimes.

But never mind, here's Thank-You from me.---:D:D:D


( On your post )

Thanks everyone Suzublu, Artic et al.
Job now complete including rubber bung just putting it back together now👍

To finish the mod.....
Don't forget to get underneath and trim the flat ends of the 2 lower plenum drains off.

They are situated above the steering rods.

No need to remove undertray :cool:

Thanks Jules, just when I thought I had finished!

Not hard job just need to reach up with some snips or sharp scissors, best done off some ramps.

keep a Check
 

Do not forget to check the plenums at least once a week, if you don't then this could be your car, a local members car recently.

Spyhole mod in place ?

https://i.imgur.com/fk1UYC2l.jpg2

Couple of litres of water during the latest rainfall we had, so it does not take long for all that fine dust & debris to form a plug.
https://i.imgur.com/XlFzX9Fl.jpg3

We check ours and our customers cars once a year during servicing.
As long as plenum guard fitted & duck bills cut off underneath they won't block that often.

Just pour water down the driver's side bonnet hinge area every month or so and observe it draining underneath both sides.
No tools required just a watering can ;)

Hi Jules.
Hoping you are keeping well and staying safe, i was in your area yesterday now Wales as opened up again.

If only all members would follow a simple checking procedure, as above the spyhole mod was in place, some members are busy i presume living life & just drive the car, same car when i checked had low coolant & poor coolant cap O-rings.

Topped it up & replaced O-rings with Viton ones, in general it needed all fluids topping up.

https://i.imgur.com/35LMW0yl.jpg1

https://i.imgur.com/7X8KZZql.jpg2

Owner was advised to do checks on plenums as above at least once a week and check fluids at the same time, hopefully he will ?

Plenum Check
 

Thank you for the article and advice Artic,

I have been the proud owner of a Rover 75 SE Connoisseur v6 2,5 for at least 3 days so it is definitely something I was not aware of.

(A few days ago I couldn't spell Connoisseur........ now I drive one).

Glad I joined this site.

Thanks

Welcome to these fine cars Seymour !

2nd item to check is the radiator cooling fan.
Select AC and fan should come on straight away.

These are notorious and have a short life.
If found not working .........


Old style 3 speed with no resistor.
(life expectancy of 60 -80k miles)

Later types with resistor fitted can usually be repaired

Check through front grill with torch or see this this link for info

2 Fan types
Note a resistor kit will not fix the old 3 speed type with no resistor

Hi Christopher.
Welcome to the club, you will find all the knowledge here to help keep your R75 in good health and quite a lot of the jobs you can do yourself with the know how from here.

There will be some areas of the forum you will not reach until you subscribe which is voluntary, enjoy and ask as many questions as you like i am sure they will get answered asap. cheers Arctic.

Hi Arctic,

Just finished a plenum check was nice and dry this time. (On the contrary to the previous check when the drain was blocked..)

I noticed however that the inner drain tubes are missing on both sides of my car. Should I be worried about this and consider getting some new or used ones?

Reason I noticed is because I am currently replacing the driverside SRS sensor underneath the carpet of my 75. (Mine is a LHD model.) Sensor was completely corroded and the foam underneath the carpet was wet. So I started looking for the source of water ingress.
While taking the old sensor out I noticed the "flooring" (looks like some kind of glued on plastic?) had some signs of superficial cracking and a hole at the rear seat area. Sealed the hole up with some silicone sealant and treated the entire flooring surface with liquid rubber just to make sure...

However I'm not convinced the flooring was the main source of water.. (I noticed after a rainfall water was coming from the front of the car downwards to the rear. I say downwards because my car is parked on a slope with the front of the car being on the high side.)

Whilst looking around on this nice forum I noticed the scuttle plugs could be the culprit as well, so I went ahead and sealed around them with some sealant just to be sure. Seeing the inner drain tubes mentioned here I wonder if these could have anything to do with my issue?
Maybe you have any other tips?

Thanks in advance!

You should post your questions in the technical forum and not here.--:D

Otherwise folk looking for answers to their plenum problems have to wade through lots of non relevant posts to find what they want.

Some of the old hands are a bit guilty of posting in here too.--:eek:---:D

Hi Colvert,

You're right. Suppose that's how this thread ended up in a 43-pager :-)

Anyhow, I did find out the source of the leak. My 75 was afterfitted with an LPG installation. Apparently whomever installed it one day thought it was a good idea to pass the control button wiring of the lpg kit through the plenum to below the dash on the driver side. I suppose the hole he used is one of those mentioned that should have been fitted with a rubber bung originally (clearly was a factory made hole, even had a hole foreseen in the plastic cover beneath the dash). Man in questioned decided to seal it all up with an inefficiently supplied plug of silicone kit. Remainder you can guess from there on..

If you are referring to the sunroof drains then that is a different story, and they would need to be replaced asap. ? link below about sunroof drains.

https://www.the75andztclub.co.uk/for...d.php?t=118622

Excellent instructions
 

Thankyou for this - easy to follow instructions, and yes, the drain was full of gunk. Couldn't believe how much water came out! I suspected it might be blocked when I started getting water in the footwell. Mind you, there's been a LOT of rain recently. I bought the pipe bending spring from Screwfix, but instead of a bootlace and tube, I adapted a lambing aid I found in our local farm supplies shop, cut the Y piece off, rerouted the flex and it did the trick nicely. Thanks again!

https://www.suppliesforfarmers.co.uk...8aAgQ9EALw_wcB

The water/gunk/rubbish comes into the plenum from the right hand side as you look at the engine bay - top right - where the plenum guard sits in a U shaped section - many members put fish tank filter material here - snug under the bonnet strut to stop gunk/rubbish getting into the plenum :shrug:

No, mine doesn't have a sunroof. I was actually referring to the ones above both wheelarches. In the meantime I actually put a bit of electrical tubing to replace both. Seems to do the job just fine.
Funny thing, after I sealed in the bits of tubing I found one of the original rubber drains underneath the side of the car, must have pushed it out from behind the wheel arch when putting the tubing.

Plenum clear out
 

Finally got around to clearing out the plenum drain tubes on my ZT mk2 at the weekend - what a state they were in!


A few observations from me.

1 - not sure the spyhole mod will work on the diesels, as one of the three cable bundles runs right in the line of sight between the hole and the drain tube. I'm thinking about using a length of plastic piping (drilled to allow drainage) to aid access from the spyhole.
2 - the drain hole beneath the servo can be clean from on top, rather than rummaging around in the undercarriage. I used a flexi aerial from my old 400, shoved that in the hole (blunted end first) and then slid the spiral pipe bender over the top. Job done!


I now have a very clean and shiny plenum, which hopefully will stay that way. I've taken a leaf (pun intended!) from my Mondeo and fitted aluminium mesh (Isopon) behing the grills as well as the fix everyone else is doing at the wiper mechanism end.



Another thing, which is a bit of an aside. Changed the pollen filter while I was in there as it looked like it hadn't been changed for about a decade. Miraculously today, the temperature gauge hit midway for the first time since I've owned her (Feb this year). It this a bit of a coincidence or could it be related? Wondered if the blocked filter could have been contributing somehow. I've got the new in-line thermostat from DMGRS to fit at some point to go belt & braces, so that job can be shelved until the spring.

You've still got to get underneath to trim the flat ends off the plenum drains if they have not already been done.

Also the temp gauge reads midscale between 74C and 116C by design.
I suspect your engine is running high 60's low 70's and stat well overdue a change.

Read about the dash diagnostics here and get an accurate engine temp reading.
It should reach 88C after 7 miles

Thanks Jules
My trip screen displays 'err' when the engine's running so doing diagnostics on the run might be a bit tricky. I can access the diagnostics when the engine isn't running, so maybe I can do a check after tonight's run home.


As for those pesky plenum tubes, that'll be a job for another day - too big to squeeze underneath and no axle stands at the mo!

IPK will still go into diagnostic mode even if ERR showing.

Sounds like it's had LSM module change without being programmed via T4.

We can cure that for you ;)

You selling your services again Jules!
Bit of a trek for me to North Wales at the moment. Dealer I bought her off thought that was the case.

:o
Owners travel from all over to see us.
This Belgium and Oslo were 2 last year !!

Most come from South East and South West as there don't seem to be any specialists in those areas.

Jules you are in lockdown again from Thursday i am told by my Daughter whom lives in Conwy, so it will be at least six months before anyone will get into Wales i bet. :mad:

Hi Mike.

Have no doubt the spyhole will work on the diesel use one of these below.:D

These are the drain tubes from the inner wings, cut the lower plenum tubes of the same from under the car;)

also add some netting to stop the debris.

You could also use some fish tank filter.

Yeah mad times.
However I've still got plenty of local owners who need MOT work which is allowed !;)

Even if no more cars set foot here for a while it would give me a chance to catch up on restoring my own stock of 75's which have been waiting for a number of years, so still plenty to do :o

Thanks for the extra pics Arctic. Will have to have a play around with those drain tubes when the weather perks up again. I think my tubes may have been trimmed already as I ran an inspection camera down to see what they were like. No real sign of the flattened end, just a gentle taper down to probably a 8-10 mm opening.



I'm guessing the drain hole in the inner wing on the passenger side is supposed to have a tube fitted. Mine hasn't, so I'd better get that sorted.

With the drains trimmed the outlets are more like 20mm dia

Thanks for this guys. Mine was pretty clean to be fair with no sign of water pooling but the drain hole was properly caked with dirt, a quick rodding and a hoover and all's well and good again. I didn't do the mod as it took me so little time to dismantle it to be fair but thanks nonetheless.

Plenum Season Started.
 

Once again plenum season is upon us, rain, leaves, wind, dust etc, so make sure you keep leaf debris to a minimum, rod at least once a week, and add some fish tank sponges, or netting to both sides of the outer wing.

Cut the ends of the plenum tubs under the car and in the wing area.

use some pliers to pull out the tube.

Also do the spyhole mod if you do not have it done. ;)

are we all checking the plenums over the festive season, if not please do so.

I know i am repeating myself but with the storms coming up, don't forget to check those plenums, did mine today along with all the fluid checks and tyre checks ;)

Plenums we hear so much about them and the reason why is very clear below in the photo's that follow.

And even more important this time of year with the Autum leaf fall etc.


Yesterday a member of the club Mike came to have his handbrake mod fitted, as i always do i checked the plenum's after asking if he had checked them it turned out he had only brought the car Sunday so the car was very new to him, he had looked at the plenums from the drivers side and could see some water and he also heard the sloshing sound when driving.

The results can be seen below so come on gents lets keep on top of these plenums do the spyhole mod and its only takes 2 minutes to check for water once applied.

Pic 1 water at least 3" deep
https://i.imgur.com/kAtHJbNl.jpg1

Pic 2 The water must have been deeper at some stage according the the pollen filter marks
https://i.imgur.com/kAtHJbNl.jpg2

Pic 3 starting to rod the plenum tube to clear the soggy leaves and dirt which as bunged up the lower tube
https://i.imgur.com/OLMliq7l.jpg3

Pics 4 the water starts to flush out of the plenum this went on for at least 2 mins
https://i.imgur.com/lj2Eghfl.jpg4

Pic 5 Still pouring out strong
https://i.imgur.com/8jm9IEWl.jpg5

Pic 6 slowly stopping with the rain we have been having this so easly could have been worse ECU damage which would have been a crying shame as this MGZT as only 20000 mile on the clock.
https://i.imgur.com/z4u6LeKl.jpg6

Pic 7 All the water drained away this should not happen again as the spyhole mod was put in place and Mike shown how to rod them each week at the same time as checking his oil water etc.
https://i.imgur.com/CJWtq4Nl.jpg7

So lets get checking the plenums right away there is no excuse ;) not to, all the best Arctic.

This is how you can check your plenums if you have never checked them before this is mainly for new members that is why i have put this thread together so it is all in one place on how to check and also add the spyhole mod & leaf stopper/collector if you so wish, in my opinion worth doing.

This is the windscreen scuttle panel/outer grille which will have to be removed to start checking the plenum for water ingress below Fig1
https://i.imgur.com/y0eKwQal.jpg1

First peel off the weatherstrip up to the wiper fixing point at least Fig2
https://i.imgur.com/zQRvDGrl.jpg2

Now you can press in the plastic spring clips to remove the grille panel Fig 3
https://i.imgur.com/iVa6WErl.jpg3

This will then allow you to remove it and store it safe for the time being Fig 4
https://i.imgur.com/XFAGyhnl.jpg4

Next step is to remove the front screw/clip sometimes you may have to prise this up if it will not screw out.Fig 5/6
https://i.imgur.com/cQLPiSDl.jpg5

Now removed put this safe also
https://i.imgur.com/V3OmKQIl.jpg6

Next prise up and remove the rear scuttle clips hold your finger over the top because these can fly off sometimes never to be found again Fig7/8
https://i.imgur.com/3GxCUaUl.jpg7

https://i.imgur.com/36VqgjQl.jpg8

Remove the first three of these and again put them safe for re-fitting after Fig 9/10
https://i.imgur.com/l9OttLll.jpg9

https://i.imgur.com/Afnzfy3l.jpg10

This will now allow you to lift the front of the scuttle and get access to the shield panel tray which needs to be removed. Fig 11
https://i.imgur.com/VNrkZaZl.jpg11

You can grip and remove the shield panel tray and slid it carefully out from its recess Fig 12/13
https://i.imgur.com/bU2smo5l.jpg12

https://i.imgur.com/dAiXCegl.jpg13

This now exposes the lower plenum and pollen filter area this is also where the ECU resides and can get damaged if water is allowed to build up because of the blocked plenum tube Fig 14
https://i.imgur.com/J7IDIewl.jpg14

Here you can see how i have rodded the tube with my choice of rodding tools a plumbers spring pipe bender 10mm or 15mm also note even though i check these every week that because of the deluge of rain we have had this year and month water is still getting to a certain height from the line seen on the pollen filter, this was empty when i took these photo's but must be filling even though clear because of shear volume of water Fig 15
https://i.imgur.com/tfwYkHLl.jpg15

This shows the rodding tool i use pipe bender with a boot lace and plastic tube the reason why will be seen later in the thread. Fig 16
https://i.imgur.com/8GCiuFml.jpg16

The shield panel tray can now be re-fitted back into place Fig 17/18
https://i.imgur.com/p4hvJUCl.jpg17

https://i.imgur.com/aIV07I5l.jpg18

This photo shows the spyhole mod so the plenum cab be checked and rodded in the future with out having to remove the scuttle clips and trays. Fig 19
https://i.imgur.com/AwKerZ0l.jpg19

Here you can see the rodding tool again in use showing why the lace and plastic tube is needed because the plenum is at least 24" deep Fig 20/21
https://i.imgur.com/ajRhFyol.jpg20

https://i.imgur.com/ajRhFyol.jpg21

Here you can how the spring as come all the way through the plenum and the tube until it reaches the ground under the car Fig 22
https://i.imgur.com/Jc4V2Qbl.jpg22

Once rodded and if you have the spyhole mod in place fit a rubber 25mm bung which can be easily removed rodding in the future Fig 23
https://i.imgur.com/aIV07I5l.jpg23

Replace the front screw clip Fig 24
https://i.imgur.com/uGN2f86l.jpg24

Replace the three scuttle back clips Fig 25/26
https://i.imgur.com/PMd4prZl.jpg25

https://i.imgur.com/TiQnrwll.jpg26

Next replace the rubber weatherstrip Fig 27
https://i.imgur.com/zQRvDGrl.jpg27

And last of all with the job finished refit the windscreen grille panel Fig 28/29
https://i.imgur.com/XFAGyhnl.jpg28

https://i.imgur.com/y0eKwQal.jpg29

The plumber spring i use with lace and plastci tube attached for the extra length needed to get to the bottom of the plenum 10mm or 15mm obtained from Toolstation, Screwfix, B&Q etc Fig 30
