Greetings all,

A few weeks back I replaced my engine and transmission mounts on my 1979 300D because of a problem I was having with the engine accelerating when going up a steep short incline (like that of a driveway or parking entrance) as well as with hard left turns. It seems in the time that I had owned the car that the issue was getting worse and more frequent. On the advise of a few board members I replaced the mounts. While the problem seems to have lessened somewhat it is not gone – and it is bugging me to no end. As I am sure most will agree – the only time I want the engine to accelerate is when I am stepping on the accelerator pedal.

I noticed while I was under the car that there are these engine shocks (which you have to disconnect to change out the mounts) and I was wondering how these play into the mix. They look like they are original engine shocks and bushings. Could this be the reason for my problem? How much of a roll do the engine shocks have in supporting the engine and keeping it from moving around?

I want to get this situation (as well as a few others) worked out before the warmer weather hits and I have to start making a few longer road trips.

Some other notes – the old engine mounts were in good shape. They were only slightly compressed with no tears, mushy spots, or cracks. I still replaced them as by the time I was able to inspect them they were already out of the car.

Like I mentioned I also replaced the trans mount. Now it doesn’t seem like this part would really have any impact on the problem described but, I don’t know that for sure either.

Also – when I turn left while at speed I feel some vibration that wasn’t there before.

I do plan on getting the car up on jack stands again this week to inspect again – but I am at a loss here. I mean engine mounts are a PITA to do but it’s not rocket science. I really want to solve this problem so I can move onto other equally fun jobs like the rear suspension and take some road trips.

Appreciate the help.
