well. after my waterpump failed on my 77 f350. I now have a large oil leak. I repalced the oil pan seals today and the leak is still there. the truck has a 400ci motor with a np 4 speed trans.
right now it appears to be coming from the bell housing and the plate that attaches to the motor behind the flywheel.
Would this mean its a rear main leaking? or is there any other gaskets that could cause this?
If I where to have a shop repalce this what would the cost avarage?

 

sounds like it could be a rear main or an improperly seated oil pan gasket. as for the cost of a shop, i dont have that answer.

 

well I looked under the truck and the leak appears to be coming from the bell housing. no oil is on the oil pan or around the oil pan seems. so I belive is the rear main now.
does this truck have a 2 piece rope or rubber seal? the motor is a 400ci
