Do you have oil on top of the A/C compressor? If so, you have one of the classic M30 oil leaks. The bracket which holds the crankshaft sensor in position is bolted to the front of the engine with two bolts; a long and a short bolt. The long bolt also passes through an oil channel in the block. Over time, the longer bolt loosens and allows oil to seep along the threads and onto the top of the A/C compressor. The solution is to remove both bolts, clean, apply threadlock compound, then re-tighten.


I was wondering if anyone can help me solve an oil leak that is comming from a '89 735il.Whenever the car sit overnight,oil leaks from somewhere. When the car is on a lift at the shop,there is no oil trail comming from any where on the oil pan or from any place from the filter canister.But if I put a container under the car where the oil plug is,the next morning,theres oil in the container.This is driving me mad! I even put a new plug and gasket just to make sure that its not comming from there.Any advice would be helpful to me on what other areas that I can check to find the leak.Also,the car isnt using anymore oil that before.Thanks...
