Engine mount polybushes, my initial findings

You won't be able to tell be looking at the bushes as they are inside the bracket. They don't seem to wear as much as they just go soft. But they are already too soft if you ask me.

The problem with Rover was the need to provide vehicles that felt modern when driven but were just re-hashed old vehicles. This led them to cut corners or at least make what they had in the way of parts work. Things like engine mounts are expensive to designed from scratch so instead of designing new they appear to have simply softened the rubber in an older existing design. It's fine for a refined feel when the vehicle is new but long term durability is compromised some what. On the plus side it's easy to rectify

There is another thing with the K series engine, being light weight alloy soft bushes help damp out vibration and so reduce fatigue failure of the block!

Bleddy Rover. But say what you will, they're a ****load easier to fix than modern lumps and drive as nicely when in good shape

. But what kind of regular owner is going tp put up with undoing four bolts to put new bushes in? Easier to just go on Honest John and bitch about it.

I'll never fully trust it, but it's me motor and it is what it is.

In addition to this thread I thought it may be a good idea to post my findings about the oem engine mount bushes.

i bought a new one which cost me £48 and upon removal of the old bush (the large one) found it had a part number on it (W17686-5) this is only available in Poland (for some reason?????) for the equivalent of about £20. the part number they use is TED 00603794.

the smaller bush has no part number on it but it can be sourced in the UK although you probably won't need it as it very rarely causes any problems.

i have removed the small bush, which is in great condition, and i am going to re-use it in the top mount as that one is weak on mine.

I just used the poly bush in lower tie bar. My V6 doesn't vibrate with it. Although I can't say the same about my inboard CV joints

I used them in both upper and lower, the vibrated to begin with but have now settled in very nicely.
