This is the rocker cover gasket, which seals the cylinder head on small engines so that the engine doesn’t develop leaks. Periodically, a gasket may deteriorate with heavy use. To maintain good engine performance, the rocker cover gasket needs to be replaced with an OEM certified replacement. This type of gasket is most often found on lawn tractors. Replacing the original gasket with the new one is a simple and straightforward process. There are four bolts holding the valve cover in place. Simply remove them and the old gasket, which will likely have to be scraped to get it completely off the cylinder head. Place the new gasket exactly over the metal frame of the cylinder head—it should fit perfectly. Hold it in place with a small amount of RTV, a silicon sealer that is impermeable to oil and gasoline.
