Hi,

I have a 1985/1986 190E, with the 2.0 M102 (this is identical to a 2.3 but with different bore or stroke).

About 18 months ago, the exhaust-side engine mount failed, I believe because the power steering pipes were leaking onto it (this is a right hand drive car so that can happen!). The car vibrated badly on acceleration.

We replaced the mount with a genuine Mercedes part, and replaced the pipes. The power steering no longer loses its fluid so it's not leaking any more. All was fine and smooth for 2 months, but then that new engine mount started rattling and clattering loudly at idle (the bolt that goes through it had come out) and the whole car was vibrating on acceleration again. The rattling was from inside of the mount.

So we replaced that one with another genuine one (free replacement from Mercedes), which lasted a bit longer but failed again, unbelievably. It rattles if you go over a bump, and the whole car vibrates really badly when you accelerate.

What could be causing this? My dad tried to claim it is my driving style, but he is talking crap quite frankly. He suggested we fit the one from a 2.3-16 (which is the same as from a 300E) - something to do with it being tougher. But would this work? Is it the right size? Would it affect the vibration damping properties because it's for a different weight of engine? I don't think it's a good idea but I have no ideas for why the standard mounts keep falling apart. The car is awful to drive when it vibrates like that so it is just sitting unused
