DNJ® Engine Valley Pan Gasket Sets are specially designed to seal the lifter valley area located between the cylinder banks on V-type engines. These gaskets play a crucial role in preventing oil, coolant, and vacuum leaks, which can lead to performance issues and contamination. Each set typically includes the valley pan itself along with necessary gaskets and seals for a complete installation—such as intake runner gaskets, end seals, and related O-rings—depending on the engine application. Designed to match the original equipment specifications, these gasket sets ensure proper fitment and reliable sealing.
DNJ® Engine Valley Pan Gasket Sets are manufactured using high-grade materials chosen for their sealing effectiveness and thermal resistance. The valley pan is typically stamped from corrosion-resistant steel or aluminum to provide structural strength and effective sealing across large surface areas. Rubber-coated metal or silicone-molded end seals offer flexibility and durability, especially in areas exposed to expansion and contraction. Fiber or graphite gaskets provide excellent sealing on irregular surfaces and maintain integrity under high temperatures and pressures. Every component is produced to meet or exceed OEM quality standards, ensuring dependable performance under demanding engine conditions.
DNJ® also offers a wide range of related components to support full engine gasket service, including intake manifold gaskets, cylinder head gaskets, valve cover gaskets, complete engine gasket sets, and more.
