Help! I have a 200 six in my 1974 bronco. I have rebuilt the motor from the bottom up. its has a ford six cam with a big valved late 250 head,header and webber. Its runs great!
Heres my problem. I have replaced the rear main and pan gasket 3 times! I have had the engine out twice. I can not stop it from leaking.
the last time I took the motor out i sealed the flywheel bolts and put in a NOS ford two piece seal. It now seems to only leak when the engine is not running. I am getting oil into the bell housing.
I know that the valve cover on these motors leak and I have put a new cover on it and put rags aroung it to make sure its not coming from there.
The crank has not ever been turned on the rear main seal. It still has the little groves in the seal area on the crank. I have not been able to find anything on the this tech page to help me!
I had the same problem before I rebuilt the engine. but this is a differnt block . the crank is same.
what am I doing wrong?
