DNJ® Engine Valve Cover Gaskets are engineered to seal the area between the valve cover and the cylinder head, preventing oil leakage and protecting vital engine components from contamination. The valve cover—also known as a rocker cover, cam cover, or cylinder head cover—encloses and safeguards the valvetrain while retaining engine oil. Depending on the engine size and application, each DNJ® product includes one or two gaskets specifically designed to seal the outer perimeter of the cover. These gaskets are manufactured for a precise fit and easy installation across a wide range of domestic and import vehicles.
DNJ® Engine Valve Cover Gaskets are manufactured using premium materials selected for durability, oil resistance, and temperature tolerance. Molded rubber and silicone rubber are commonly used for their sealing flexibility and long-term performance, while certain applications may feature metal-reinforced rubber for enhanced structural integrity. Cork-rubber composite materials are utilized in earlier engine applications due to their excellent conformability. All materials are rigorously tested to endure thermal cycling, engine vibration, and oil saturation, and each set is manufactured to meet or exceed OEM quality standards.
DNJ® also offers a full range of related sealing components to support comprehensive engine repairs, including valve stem seals, intake and exhaust manifold gaskets, cylinder head gaskets, complete engine gasket sets, and more. With precision engineering and top-tier materials, DNJ® Engine Valve Cover Gaskets deliver exceptional performance and long-lasting durability.
