Greetings Ford Six Fans,
My 250 with the aluminum CI head has been running for about eight months now, and I've had the valve cover off several times to tighten the valve lash (hydraulic cam with adjustable rocker arms). Have a stamped steel "Power by Ford" valve cover and have always used cork Fel-Pro gaskets and torqued to stock specs. I do have studs (1/4" SAE), rather than bolts, to hold the valve cover down. Use Perma-tex red high temperature sealant.
Each time, I clean the valve cover mating surface on the head and the mating surface of the valve cover itself thoroughly, removing any visible gasket residue and also wiping it down until there's no oil residue. However, there is always some oil seepage between the gasket and the valve cover and/or the head - the gasket eventually looks as though its been soaked in oil. I should add, however, that no significant amount of oil leaks out ... the oil level on the dipstick (Joe Gibbs HR-1 oil) never changes appreciably.
Am about to pull the valve cover off to tighten the valve lash yet again, and also to repaint the valve cover (coolant was splashed on it from a radiator hose leak slung up by the fan, and the dark Ford blue paint has been discolored somewhat in spots). Have decided to try a rubber valve cover gasket this time - any other tips on achieving a better valve cover gasket seal?
Thank you,
Bob
