This valve cover gasket seals the joint between the cylinder head and the valve cover on the host tractor engine. It prevents oil leaks and keeps contaminants out of the valvetrain area. A degraded gasket allows oil to seep past the cover, which can lead to low oil pressure and dirty engine compartments. The gasket is manufactured by AGCO to match the original sealing profile and groove geometry of the cylinder head, ensuring proper compression when the cover is torqued to specification. On reinstallation, clean both sealing surfaces and replace the gasket to maintain a leak-free seal.
