leaking...f...king valve covers ???

If you slowly peel the gasket from the bottom up one or 2 things will happen the entire gasket will peel away from the head and valve covers or the gasket will stay sealed to the valve covers and peel off of the heads . I've done this many times but you have to use the copper stuff . Any other sealant will tear the gasket and or stick to the head leaving chunks of gasket and sealant. All I do is run a clean rag with carb and choke cleaner over the copper sealent/gasket surface and apply a thin layer of copper permatex sealant over existing sealant and bolt the valve covers back up and still no leaks!
