Quote: was the seal in the timing cover that seals to the end of the crank replaced? If I remember right you said the old crank was mushroomed.
Yes, all seals replaced...removed timing cover, found crank seal pushed up against crankshaft. Installed seal into cover again, re-installed, started, pressure climbing through 50 psi, then fell back to around 15. Pulled timing cover again, seal again against crank. REALLY seated seal this time, then realized, HEY there's a groove there for a snap ring to hold the seal in...OH, I remember that snap ring, it's laying right here...installed snap ring and timing cover, now oil pressure is 80 psi cold, 75 after heated. Took for 7 mile ride, never fell below 75 psi...DUH.
