ok the car has been sitting all winter long and gets the occasional start up...i have noticed a very big puddle of oil under the car....if its sitting it shouldn't be the rear main right more then likely the pan has a hole or leaking right??? im trying to track it down and i crawled under it and there is oil all over the pan around the bell housing its everywhere down there any ideas where it could be coming from....when i first got my 93 it had a leaking problem and it had two huge holes and was jb welded there was so much on the inside of the pan it help about a 1/2 qt less then it needed too
