The cylinder head cover gasket forms a compression seal between the valve or rocker cover and the engine's cylinder head. Its job is to prevent engine oil from leaking out of the top of the engine while also keeping dirt and debris from entering the valve train area. When this gasket deteriorates, cracks, or is compressed beyond its service limit, oil leaks develop around the top of the engine — leading to oil loss, potential fouling of nearby components, and increased fire or smoke risk if oil contacts hot exhaust surfaces. Replacing the gasket at the first sign of seepage keeps the engine clean, oil levels stable, and the equipment running as intended.
