Marcus, I've seen this problem a couple of times and it has never "cured itself". First, be certain it's engine oil. If you just rebuilt the motor, that's probably a good guess. I think your hunch that the main seal is shot is probably correct, but I bet its because (1) the seal was not install correctly, or (2) the gland nut was not put on tight enough. Number 2 is more common, IMHO. You've got to torque that baby to 200+ (252, I seem to remember is the official number) ft-lbs. Otherwise, the flywheel loosens up and ovalizes the dowel pins, wobbles and breaks the seal. I've been through this, and its not a pretty site.
