So I'm doing a top end now and also replacing the one way bearing. After I replaced the one way bearing the crank shaft only spins one way. It does spin the correct way ( like the way it goes when the engine runs). If i try to spin it the other way it dosent budge at all. I don't know if it should spin freely both ways or only spin the one way. Again, It spun freely both ways with the old one way bearing, but that bearing was broken so the crankshaft acted like there was no bearing at all. I want to get this engine together asap so help is apperciated.
