Default Lower Engine Mount OEM vs Others.

As some of you may know we or you may have had trouble with the lower engine mount on your R75 or MGZT and the difficulty in obtaining the OEM mounts and the cost of them if you have been able to obtaim them. I/you/we have gone down the road of trying powerflex mounts Red for diesel and Yellow for petrol with some good reports and some not so good reports of there use.
Some members have reported bad vibrations some have reported that the car is now smoother so the real reason for this thread is to try and gauge what and how the engine mounts you have fitted are working with your car now in the past and the near future.
Another reason is there is a new mount on the block so to speak from (roverlink)a chinese mount used on the Roewe/MG i am at the moment testing one of these and must say first impressions are very good no vibrations smooth gear change and also it is as near to the OEM mount as you can get if not better.
I am in talks with powerflex and Brown & Gammon at the moment with regards to the Red and Yellow mounts which i will reveal later after they have got back to me over a certain problem i/we have had with the mount,they have informed me of modifed or newer version which is in the process of being made and have also asked me to road test a couple which i am willing to do and report back to them and you the members.
But at the the moment we are testing three kind of mounts well four if your including the new OEM mount on my MG ZT

Powerflex Red Diesel mount with a original metal and nylon insert from a OEM mount on trebors car cheers Rob.fig 3

Hopefully this last mount (roverlink) is going to be the one which will out last the cars life but we will see in time, please feel free to add your thoughts you have experienced on this subject and if you have any good or bad points on any or all of the mounts involved that way we can gauge which is best of the bunch cheers Arctic

I replaced my OE engine stabiliser with a brand new OE engine stabiliser, and it really made hardly any tangible difference if I am honest.

The diesels vibrate, thats pretty much it. A knackered mount will give you clunking and excess engine movement.

Dont forget, the diesels vibrate more when they are cold, and are much smoother when up to temperature.

As for the powerflex, well, you have to be a bit special to fit one to a diesel surely? It can only make the vibration worse than a standard one!

Ok it made a TINY bit of difference, but the most difference is between cold and warm engines.


Looking at the construction of the Chinese one vs the Rover OE, I cannot see how there can be any performance difference between 2 new ones. They are literally identical for all intents and purposes.

Ross hopefully the (roverlink ) one will be either slightly better given the difference of the rubber insert makeup there are a few members including myself testing or have one fitted at the moment and i have found that the vibration is less with the (roverlink ) one when starting from cold compaired to the OEM one, also to be taken into consideration is if the lower wish bone bushes are in a good condition somehave split this will add to stress on the lower engine mount.

If you are going to do a comparison, it might be worth also including the popular adaption of the Modeo lower mount too. I have had one on my CDTi for around two years now and no issues at all.

If I were replacing now, my inclination would be to try the Chinese mount, because assuming it caused no vibration issues, the built in limit buffers suggest it is likely more robust than the OEM unit. It is the lack of the buffers and extra movement, which causes the OEM units to split.

Hi Arctic

any views yet on the Chinese Roewe mount on a CDTi? I have the pink PF and it seems fine but given some of the recent experiences thought I might get one of teh Roverlink mounts in stock in case!

The lower engine mount is indeed subject to twisting forces(pushing to one side)
This is why i switched back to rubber. I suspect the poly does not handle sideways forces so well. In fact, the mount appeared twisted to one side. The poly bush was developing looseness inside the mount too.
So i am trying the chinese rubber mount now.

Default Modifed Powerflex Diesel Mount.

As some of you know i have been in talks with powerflex for a months or so now with regards to the Red Diesel lower engine mount which in a few cases have failed posts and photo's in the thread.

Two days ago i got an email from the sales manger informing me that the modified diesel engine mounts had been made up and he was sending me out two to test and to replace the ones that failed,well this morning they arrived.

As you can see from the photo's the colour as changed to Yellow three elongated sloted holes have been added the rubber composite is stiffer and once fitted into the alloy teardrop mount there would be no void as was in the red original mount.

I myself am in the thinking that these changes are more towards the petrol engine mount but with sloted holes so its not to stiff and hoping it will solve the problem of the mont tearing its self out of the mount, also it might be that no Yellow mount as been reported to have failed like the diesel one as albeit on a few occasions.

I will reserve my full judgement untill one or both have been tested for a few months at least what are your thoughts on the mount photo's below cheers Arctic.

Figs 1/2 show that the metal centre is the same the middle rubber is now the same as the petrol engine bush no void but still the lip is very low.

2

Figs 3 show the contrast to the original Red powerflex mount
3

Fig 4 shows the close up of no void in the middle of the bush hoping that it will stop some of the movement.

Fig 5 face on view of the two mounts
5

Fig 6 next to the Chinese (roverlink) mount which at the moment seems to be performing very well less vibration smoother gear change mind on my Tourer that could be down to having a full new clutch fitted a few day ago.

Please add your opinions on what you can see so far cheers Arctic.

So far as the diesel mount goes, I think there have been a few reported cases where the mount has been offset with regards to the chassis bracket, once the mount is attached to the engine. Mine, which as already said has been faultless with the adpated Mondeo mount for the past 2.5 years, all lined up perfectly - both side to side and front to back.

I would imagine that any offset in the mount, will cause the Powerflex bush to tear.

A little more information which might help the discussuion....

I have a spanner which I made up specially for the job of changing the belts on the CDT, to enable the tensioner to be released. I have loaned it out several times since I made it and all managed to use it fine, except for one case, where it had to be returned unused because it was reported, that it would not fit in the gap.

I know the gap is tight, but it certainly should not vary from car to car.

Getting to the point now - I wonder if the above problem with the spanner, plus some of the reported offsets in the lower mounting bush and the Powerflex bush ripping, might be related?

Could the problems be due to one of the two upper engine mounts having failed, or there been some serious accident damage to the chassis?

Could some of the continueing reports of vibration even after bushes have been swapped be due to any of the above issues?
