Check your tranny fluid level just to be safe - but I would bet it is
the seal at the crankshaft. Instead of being labeled "crankshaft seal" I
think it is actually called a "Flywheel Seal" if I remember correctly.
Bob Donalds of Boston Engines has a short video  available that shows
the proper removal and replacement of that seal, along with information
about how to avoid damage when removing and installing. Good video. Good
guy for putting it out.
