“Really, you don't think the valve cover has been off the engine once in 30 years? My guess is a previous owner did the RTV hack job.”
I purchased thee jeep from the original owner who is a friend of mine. He does not recall ever pulling the valve cover.
I reviewed the Haynes Manual prior to removing the valve cover. It instructs you to re-install the valve cover with a bead of RTV only.
My question was. “Should I put it back the way it was with just RTV, or use the gasket plus RTV”
I assume from your response, you would use a gasket.
Any other suggestions?
