Default Powerflex diesel bush

Some time ago, I have fitted a Powerflex set of bushes for the lower engine mount.





I was really pleased with it, until I started noticing a incrising vibration coming from the engine.

Got myself under the car and this was what I've fond!





Has anyone else experienced this problem with powerflex bushes?

not yet! How long did this take?

I saw some comments a week or so back that someone else had issues with them

I have used them for years on my minis with no issues

Hoped it would be the same on the CDTi (in particular since I have upped the beans a fair bit with various mods)

I've changed the bushes approximately 4 months ago and done a max of 5.000km.

Recently I have upgraded my turbo to a bigger one and in the first days the new turbo had a small leak in a tiny gasket. That was immediately taken care off, but the drips of hot oil fall directly on the bush.

Could that have caused the failure of this bush?

as its made of polyurethane I doubt it; I will now be keeping a close eye on my mounts!

That was my thought also... I have fitted a new one and going to keep my eyes open to see what's going to happen!

thinking about my minis; they spew oil out all over the place (compared to the 75!) and the Poweflex bushes have always been fine with this whereas the older ribbery ones used to last months!

Hi

I changed the large bush on my engine mount a few months back and have felt extra vibration at tick over since doing it.

Mine is a 1.8 petrol and of course I used the yellow bush.

Looking at the photos, I'd say there are signs of fatigue cracking.

The inside of the mount is not smooth, it's ribbed. My guess is the sharp edges are cutting into the bush. I'm getting used to mine but I don't think its as good as an original in good condition.

You upgraded the turbo on your CDTi? Do you have any more info?
