2002 BMW 325xi Q&A
2002 BMW 325xi Question: What is the most likely cause of an oil leak from the front of my engine.
I have already replaced the valve cover gasket. That seemed to help. However, the engine will sometimes run a little rough when I start it and the oil light comes on. If I shut the engine off after a minute and restart it. It will pure like a kitten and the oil light goes off. Could this have anything to do with the VANOS control unit? How do we find the leak? Thanks, Bill Poirier - Poiyox
