Then about a month went by and then the oil cooler seal started to leak. So fixed that. About few months went by then the rear main seal started to leak. Finally just sold the car. All i know is i was driving about a year with no oil leaks till i switched to synthetic and then the nightmares began.

Holy crap! Good thing I read this, I was planing to go to walmart to get some motorcraft syntetic for my saturn. Syntetic is probably liquid texture that can pass through gasket.
