DNJ Engine Components VC3137G Valve Cover Gasket Set with Grommets

The DNJ Engine Components VC3137G is a complete valve cover gasket set with grommets designed for the GM/Isuzu 3.7L L5 DOHC 20-valve engine (LLR). Engineered to seal the area between the valve cover and the cylinder head, this set prevents oil leakage and protects 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. When this seal fails, oil leaks can lead to burning smells, fouled spark plugs, and potential engine damage. The VC3137G restores a clean, leak-free seal.

What's Included:

• Valve cover gasket(s) for the outer perimeter seal
• Spark plug tube seals (where required)
• Valve cover grommets (where required)
• All related O-rings for complete installation

Key Features:

• Manufactured using premium materials selected for durability, oil resistance, and temperature tolerance — including molded rubber and silicone rubber for sealing flexibility and long-term performance.
• All materials are rigorously tested to endure thermal cycling, engine vibration, and oil saturation.
• Manufactured to meet or exceed OEM quality standards.
• Engine details: VIN E, 20V DOHC (LLR designation)
• Backed by a 12-month / 12,000-mile warranty (whichever comes first)

With precision engineering and top-tier materials, DNJ Engine Valve Cover Gasket Sets deliver exceptional performance and long-lasting durability. The VC3137G is an ideal replacement for worn or damaged valve cover gaskets during routine engine maintenance or oil leak repair.
