1995 300D engine vibration
 

Another thread with a question on my "new to me" 1995 300D.
The engine starts and runs very well, but it's vibrating at idle...when it's running and you look at the engine you can see the vibration, you can feel the steering wheel vibrating too, when the drivers door is open you can also clearly see the vibration of the door.
It is vibrating way more than my 1987 300D engine. I have new engine mounts in 1987 so inside you can't even tell the engine is running. So is this just the engine mounts or is there some other Issue that makes the engine vibrate excessively?

Replacing the engine mounts is the best way to answer this question. ;)
I replaced them on my '95 and the difference is amazing. Of course, mine collapsed to the point of puking out the inner fluid..... :eek:

Definitely look at the engine mounts first. Bad engine mounts will definitely get you shaking ... like Jimmy's my 300D had an oozing mount a few years ago. New ones made it so I couldn't even tell the engine was running other than the sound. You could also check the transmission mount behind the transmission yolk.

You could also check the idle speed of the engine ... if it's idling very low it could be kind of rough. Though you can tell that pretty quick by looking at the tachometer.

If all that is in perfect order, and it's still shaking, I would guess maybe a bad injector or poor compression on a cylinder, but some of the other guys could probably weigh in better on that.
Check the engine mounts before anything else.:o
