Question about 1993 Chevrolet Lumina
I would recommend changing both gaskets. You must remove anything that is on top, hoses, wires ect, BUT MARK everything and make a diagram of what you took off, and also take some good pictures.
Make sure you get all the old gasket material off of the engine, and valve covers, clean the inside of the valve cover really well with solvent, and use a very small amount of permatex orange high temp silicone on both sides of the gasket, let it set up for about 10 min.
DO not over tighten valve cover bolts.
Let me know how it goes
