Replacing the gaskets on a V-type engine is a job for the pros. But you can replace the gasket on a four-cylinder engine in about an hour and for less than $25. Hereâs how to do it. Pick up a new valve cover gasket kit, a tube of room temperature vulcanizing (RTV) sealant and a spray can of brake cleaner.y dad said it was from a leaky valve cover gasket. We bought a new gasket for $20 and had it installed in about 20 minutesâit was really easy. But a few weeks later it was leaking again. We didnât know we had to smear silicone sealant over the timing cover joint.
