DJ Rock VC670G Engine Valve Cover Gasket Set

Premium Valve Cover Gasket Set for Select Nissan and Infiniti

DJ Rock VC670G is a premium engine valve cover gasket set built to seal the valve cover to the cylinder head and help keep engine oil where it belongs. It is a direct-fit sealing solution for select Infiniti G20, Nissan NX, and Nissan Sentra applications with the specified engine configurations.

• Premium-grade valve cover gasket set for leak control
• Seals the valve cover perimeter to reduce oil seepage
• Includes sealing components for applications that require spark plug tube seals and grommets
• Built with oil-resistant materials for heat and vibration exposure
• Cross-references Gates 19652 and MAHLE VS50140

Detailed Fitment and Function

VC670G is engineered for engine sealing service where the valve cover gasket has hardened, shrunk, or begun leaking. It is compatible with 1991-1996 Infiniti G20, 1991-1993 Nissan NX, and 1991-1993 Nissan Sentra, with a 1999 Infiniti G20 application also listed in the fitment data. This part number, VC670G, is intended for buyers searching for a valve cover gasket set for Infiniti G20 or Nissan Sentra oil leak repair, as well as a Nissan NX valve cover gasket replacement.

The set is made to maintain a secure seal under thermal cycling and engine vibration. Depending on the application, valve cover gasket sets can also address spark plug tube sealing and related grommet sealing points, helping restore the integrity of the top-end engine cover assembly.

Common Problems This Part Addresses

• Oil leaking from the valve cover-to-cylinder head sealing surface
• Oil residue collecting around the cylinder head or spark plug wells
• Hard, flattened, or deteriorated valve cover gasket material
• Seepage caused by worn sealing grommets or tube seals
• Top-end engine contamination from escaping oil

Installation Notes

Clean the valve cover and cylinder head sealing surfaces thoroughly before installation. Inspect the cover for warpage, damaged bolt holes, or old sealant residue, and replace any worn sealing surfaces before reassembly. Follow the vehicle service manual for torque sequence and torque specification to avoid over-compressing the gasket.

Quality Assurance

DJ Rock VC670G is a premium-grade sealing component manufactured to meet or exceed OEM quality expectations for the listed applications. The materials are selected for oil resistance, flexibility, and temperature tolerance to support long-term sealing performance in daily-driven engines.
