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.eal the timing cover joint with a small bead of RTV. Then install the valve cover and torque the bolts to specifications. Peel off the old gasket and clean the valve cover with brake cleaner and clean rags. Next, clean the gasket mating surfaces on the engine.
