Wet Carpets

AFAIK it's only the sunroof drains that do that. Never heard of wet carpets / water in the cabin being blamed on missing plenum drain tubes.

Blimey, you have some clever mice down your way. Do you think they'd be able to wire in a remote control box for my FBH? ;)

My carpets get wet and I don't have a sunroof. Drivers footwell and then rear driver's side. Plenums clear and kept clear as did my own mod. The water finds its way in somewhere!!!

Strange though after last nights downpour - dry as a bone. It seems to be long periods of rain when car is left standing for a few weeks... :shrug:

Oh dear TGB does not have a sunroof :confused: but she sure does have water where it should not be. Have just got to find/figure out where it's coming from, correction where it's getting in :p: before some wags says the Sky :smilie_re:.

I can see right through to the ground, so mine's either been circumcised or it's missing, too. I'm going to check it out because, according to information from T-Cut on the following thread, if it's missing then water can get trapped further down in the compartment and cause corrosion. I'm also worried about mice nesting in my pollen filter this winter, or worse still, rewiring my ECU.:D

my Connie tourer is the same age as yours and does not have any rubber in it and when I peer in I can see the ground (which means it cannot flood the ECU at least). I had not thought there might be a lower chamber but I did wonder on reading this if MGR did a late mod on some of the final MKIIs to get rid of the blockable tubes?

Arctic 5th October 2012 21:37

The tubes should be in place on all models from 99 through to the time of closure, if not there i have heard that some dealer removed the tubes :shrug: why i dont know maybe thinking its the best bet other than ECU damage if missing i would suggest replacing.

I am in the process of adding to this thread the spyhole mod, and the plenum leaf collector with pics as always so they are all in one place on a thread to save new members searching from one post or thread to another.

The first chance i get i will try and get a camera down the plenum chamber with the tube removed and see what lies below :D Arctic.

Leaf stopper/collector
 
To help stop leaves and debris from getting into the plenum below you can use this gutter netting very cheap and does the job wonderful brought from pound shop,lidil and Aldi.

One roll will do eight cars so if you are going to any meets a worth while mod to do takes about 20 mins to do both sides ;) you will need sissors four cable ties one gutter grip and a rule. Fig 1

Cut two pieces of the wire 15" long Fig 2
http://i45.tinypic.com/ejwz0y.jpg2

Next cut down lengthways and 2.5" in from the edge by 5" both pieces of wire Fig 3/4

Next trim the corner of both pieces of the netting you can do the while fitting it to the car to get a more acurate cut i am able to do it because i have a template ;) Fig 5/6

All the parts ready for fitting to the car over the wing plenum tubes near and offsides Fig 7
http://i46.tinypic.com/j0lgeb.jpg7

To fit remove the front and rear scuttle clips as in the plenum photo shoot at the start of the thread, this will help when you feed the netting under the scuttle to seal the appeture/gap over the tubes, if you did not cut the corner before you can cut it to shape now Fig 8
http://i45.tinypic.com/11ty8ll.jpg8

Once you have cut to shape and held the nett in place by the bolts holding the bonnet hinge and the gutter clip near side passenger drill two 5mm holes for the cable ties Fig 9

Cable ties attached Fig 10

A little nick in the nett so the tube can be rodded Fig 11

Neat finished job all for £1 or £2.49 the most and 20 mins of your time at home or a meet Fig 12-14

Spyhole Mod Easy To Do
 
[QUOTE=Arctic;1109189]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
http://i47.tinypic.com/2hr040w.jpg1

Below is how to do the spyhole mod you will need a rule pencil 25mm drill bit and a 25mm rubber bung Fig 1
http://i48.tinypic.com/14cd7ba.jpg1

With the scuttle shield panel removed measure 97mm and 180mm from the points in the photo below Fig 2/3

Here you can see my template which i use at meets so i can easly turn over a good volume of trays in a few minutes Fig 4
http://i49.tinypic.com/jl4awg.jpg4

With the panel marked out and your drill ready with its 25mm bit we/you can now drill the spyhole Fig 5

When you drill the scuttle tray makes sure you have support under the tray at all times Fig 6

If you intend to use the plumbers spring look for a 10mm or 15mm a boot lace and a tube mine was from an old wendy house but any 15mm tube will do 12" to 15" long Fig 15
http://i48.tinypic.com/4jm8lg.jpg15

Also grind or file the end of the spring to remove the curl so it is smooth and will easly go into the tube Fig 16
