After some inspection and such, we're coming to the conclusion that it's not the real main seal. The car does not leak when running, at least, not to the point that the real main would indicate. It seems as if the engine leaks more when off, after the engine has stopped running. There were absolutely no indications of a wet rear seal when we had the engine out. The oil pan gasket was a little moist, but it wasn't indicating anything wet either.
We have two thoughts. 1.) the oil pan gasket is leaking near the flywheel. 2.) the crankcase isn't ventilating properly and it's pushing the oil out as the pressure grows. The second one is far easier to test and we'll do that soon.
