rear main doesn't leak so i wonder if i had housing out of alignment if that seal would be out for sure or if the bolts werent tight enough on tranny and it coming loose cracked housing or if maybe there is somthing i cantt see causing all my trouble. by the way if a vibration dampener is bad what effects can that have i hear a strange growl up front at times. thanks for reading this all. hope to hear any ideas you guys might have.

Did you dial indicate the new bell housing? Should have. I was always told it will brake the crankshaft if not. I never didn't dialed one to see. Don't see it taking the rear seal out it was out till the crank brakes. Is there a support missing on back of tranny that goes from frame to frame? Tranny bell didn't fit in the engine housing right?

As the dampener, I seen alt pulleys brake and spin and oil pump gears come off. Acc. drive bushing spin but nothing ever tore up gears in a N14 yet. Weeks just starting though.

Usually if the transmission comes loose, both surfaces will not be totally flat anymore. slight differences won't cause a problem, but more times than not, if the engine housing needs to be replaced so does the transmission housing. The new engine housing, or replacement housing does need to be dial indicatored. If the lip on the transmission housing where it fits into the engine housing is worn, it will not be centered when you install it. That will also cause problems.
