In discussing the oil leak issue with the dealership that sold me the car, they faxed me the results of the PPI that a Porsche dealership had done on May 23 and it indicates nothing about an oil leak. The car had about 600 more miles on it from when the PPI was done to when I picked it up (I think one of the dealership’s owners was driving it for awhile). There was an oil change done to it just before I picked it up by a non-porsche dealership garage but it was a garage that specializes in German autos. What would be the effect if they overfilled with oil a little? Any other thoughts/suggestions?
