I had the same thing last oil change, but I thought (?)it was a leaky pan gasket.

more than likely it is a oil pan leak being blown up onto your starter and tranny.

Bad rear seal common ? no

Bad oil pan gasket? yes

could be the vent tube. look on the front P/S of the engine. you will see a tube sticking down pointing straight at the ground.. a small amount of oil comes out of there on mine, and then it gets blown to the rear of the engine/front of the tranny.. not enough to drip but it makes it messy..

Thanks Brinker007, I will check it out better before I take it to stealer,98,000 miles on it, no warranty soon.
