ok,today I drove the car about 15 miles to a friends garage[gas station]we put it up on the hoist and remove the tork con. cover.there was just a little bit of oil laying in the bottom.but there was also some right up above by the side of the pan gasket and also a little under the oil adapter.we cleaned off all the oil and ran it up on the hoist for about 10 minutes reving up and so forth,shut it off and there was no sign of any leaks at all,if it was the rear main wouldnt It have dripped somthing when we where running it.?Im very stumped.
