2001 BMW 325 mileage: 55,000. I just got an oil change and found that the oil filter housing is leaking. While getting the oil change, I had noticed that the mechanic was confused about the placement of the O-rings. Could you describe how the three o-rings are supposed to be fit? Thank you in advance.
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.
