Been reading thru the archives, but still have questions:

When warm, my 83 300CD will shake a lot at idle and after 10-15 secs. mostly stop shaking.

The 12mm dampener screw shows no threads between it and the 14mm jam screw between it and the inj. pump. So, looking at how close the oil canister is to the back of the pump, do I have to remove the canister to replace the dampener screw?! If so, is this relatively easy or tricky? Incidentally, the car started this shaking a couple of months ago and there has been no engine maintenance for 4-5 mos.

Looking for some insight. Thanks!
