Oil leaks from under the car can be a number of possibilities....Didn't get if your car had a turbo or not. If it does, it could be the oil return line of the turbo...a simple and cheap fix. If it's the rear main seal, it's a tedious and expensive job...the transmission has to come loose from the engine. Also, it might just be a bad gasket fit on your oil pan bolt. I had a leak last week and it was the aluminum washer on the bolt I just mentioned being off center. When I changed it out, th leak stopped. That's like a 5cent piece....Ask your friend to look there first, and if nothing is found, ask him to clean off all the oil from under the car (steam cleaning is best but may not be practical), then drive it for 10 mins or so in a spirited way and then check under the car again. He may be able to see where the leak is this way. Good luck! ARe you loosing much oil in the engine due to the leak?
