2001 BMW 325 Repair Question
2001 BMW 325 oil filter housing is leaking
Visit the repair manuals page to find out how to describe how the O-rings fit. If we had your car here, we would compare the new O-rings to the old ones being replaced thus substituting the new ones for the old ones. If your car has proper oil pressure and the leak is fixed, then your mechanic must have put the new O-rings on properly.
