manifold leak
 

Just thought I would pass this on, had an exhaust leak in the area of the number four exhaust port. Removed the intake and exhaust and found them to be true and level. Noticed valve cover gasket protruding about a quarter of an inch above the valve cover. Apparently this caused the manifold and gasket not to seat properly against the head. The new gasket practically touches the valve cover itself, therefore the protruding valve cover gasket held the manifold slightly away from the head. At 1800 miles the cork apparently burned away and a leak developed. Cut the exposed cork gasket on the valve cover and installed new manifold gasket and all is well.
Sometimes the fix is so simple it escapes us.

Thanks for info,!!

Did you use the copper shrouded gaskets and split rings? Paul Shinn on YOUTUBE has a great video on replacing the intake/exhaust manifold gaskets.

My 30 coupe is not set up for gland rings. I used a one piece gasket with the metal on the side facing the manifold and the paper side toward the head, no gasket sealer used.

Haven’t used gland rings for years
