Any tips how to seal the distributor housing? I placed an OEM O-ring (on the part going into under the valve cover), did everything as the book says - leaking!
Any proven advise? Non-OEM? Put something on it? Anything?
Thanks!

you replaced the big O-ring that goes around the shaft of the dizzy that inserts into the head? thats all thats needed

There is supposed to be some FIPG around the corners of the halfmoon hump where the valve cover gasket touches the distributor collar. I think FIPG actually goes between the collar and the head as well.

I would suggest installing the distributor with the valve cover removed and the two bolts on the collar/bracket loosened, that way you know you arent pinching the oring while inserting the distributor.
