Unhappy Uneven Compression 16V

I have a 1986 190E 2.3-16V with 156,000 miles. It has been well maintained and a very reliable daily driver. It started having a vibration at idle and certain RPMs. I replaced the engine and transmission mounts and they helped the problem a little bit. I did a dry compression check (engine warm) and the results were as follows: 1-125psi/2-150psi/3-145psi/4-150psi. Wet compression results are as follows: 1-150psi/2-160psi/3-174psi/4-160psi. It looks like the #1 cylinder is worn. Is it time for a rebuild? BTW the MB repair manual states the oil pan may be removed without pulling the engine. Does this mean I can replace the rings without pulling the engine? Any advice would be appreciated.

I think that this could be a valve or ring related problem...IF the leak is small enough on the valve face, oil will help to seal it. Make sure to do a cylinder leak test to find the leak.

Thanks for the info. I will go ahead and do a CLT on the engine and see what the results will indicate. Does anybody know if it is possible to remove the oil pan on this car without pulling the engine out? The book says it is possible but I just came out from under the car and it looks like the wide back end of the oil pan where it hooks up to the bell housing will hit the cross member. Do I have to remove the engine mounts and raise the engine from above to get some clearance over the crossmember? Thanks
