Random thoughts on front oil seals:

Their job is made much more difficult by an old engine with poor ring seal. Crankcase pressure is the #1 cause of front seal leakage. We find in many of the oil pumps we rebuild the vacuum pump is not functioning and/or the road draft tube is plugged. Often the tube and fittings from the bottom of the block to the windshield wiper are plugged.

Anytime the front damper is removed, have the keyway magnaflux checked for cracks. About one in three is cracked

Before reinstalling the damper, put it on a lathe and polish the seal surface.
