Nate, I don't know about the oil seal but check the dampening plate closely (it may look like a automotive clutch plate). I have had several damping plates fail after 10 to 15 years of normal use. The small additional cost to replace it now while the reduction gear is out may look like a good investment if it is nearing the end of its serviceable life.

I will be lifting the engine into either the salon or up into the cockpit (my first time for pulling engine adventures). With the transmission already removed, this means removing the clutch plate, the flywheel, and "gently" prying out the old seal. Anyone done this repair? Any advice to offer? Our local mechanics are too busy (unless I bring them the engine) - but one suggested I buy a "slide hammer" to pry out the old seal....
