[IMG][/IMG]1981 240D has an idle shake or rattle that I am at a loss to figure out. It is only at idle. Anything above idle it goes a way. I changed the engine mount last year thinking that was the issue to no avail. I replaced the idle shock as well as the rubber bushing that mounts behind the oil pan to the chassis cross member, still there. I just noticed that the engine mounts are totally compressed to the point that the metal on the engine mount is touching the frame. I checked the part number 123 241 1213 to see if I got the wrong part and it is the correct part number. I jacked up the engine an inch and can visible see that the engine mount is no longer bottomed out on the frame. The idle rattle is gone. I’m thinking one or two possibilities. 1) a bad batch of rubber from the factory or 2) Trans mount is wrong for the car or installed incorrectly.
Please point me in the right direction. Thanks
