Where is the oil coming from?I would grab a flashlight and start looking dude. Could be your oil feed line for the turbo. Could be the return line. Could be your lower oil pan. Could be the upper. There is really only one way to find out.

I fail to understand how oil can leak while the car is off... but not while it's on.. That makes no sense what-so-ever. You sure it's not just a small leak, and maybe it's building up and then spilling all at once? Grab a flashlight and start looking with the motor running... I'll guarantee it's doing it with it running though.

Its pretty easy actually. The more hot the oil gets the thinner it is so there for it can leak out from fitting but not after it has cooled down. Never heard of people running thicker weight oil when they are to lazy to repair the leak and just need it to last?

I have the same problem. Im leaking oil out of my drain plug but only after Ive driven the car. after it sits and is cold it no longer leaks.

That means it's leaking while running too... He claims hes not having any leak while it's running... My point was, the car isn't going to ONLY leak while the car is off.

If its leaking oil its leaking oil very slow. Same goes back to my drain plug. I can look under my car for an hour and see no leaks but leave it sit over night and I have an oil spot.

You have to track down where the oil is coming from

check by the oil filter theres an oil pressure sensor. almost always leaks.

theres also your rear main seal. oil pan gasket.
