Title says it all,
I put a rebuilt 460 into my 78 about a week ago and its leaking oil around the oil filter. When it is idling it wont leak but if I drive anywhere accelerating there will be oil all over the filter, fuel pump and frame.
I get about 60 psi idling in park
40 psi in gear idling
60-70 psi accelerating

I have put 3 different oil filters on with no change.

It has a stock style oil pump.

What do you think it could be?

 

Does the engine have the adapter on it to change the angle of the oil filter? I had a 460 out of a van and it has one on it. If it does l may have a bad O ring on it

 

It doesn't have a oil filter adaptor.

Might have it figured out. Looks like fuel pump is spraying oil. I put a piece of cardboard between the oil filter and fuel pump and drove it around the neighborhood. Fuel pump side was coated, oil filter side is dry.
Bought a new fuel pump earlier, gonna install it tomorrow. It should fix my problem.

 

Was there an oil slinger on the crank just ahead of the timing chain gear? If so, did you discard it or keep in for the rebuild?
Is it the fuel pump itself that is leaking or just the gasket?
