5/16 Pontiac Valve Cover Gaskets

The 5/16 Pontiac valve cover gaskets are a critical sealing component designed for Pontiac engines that rely on 5/16-inch fastener spacing and port configurations. These gaskets serve as the primary barrier between the valve cover and cylinder head, preventing oil leakage while maintaining compression integrity in the crankcase ventilation system. Whether you're performing routine maintenance, rebuilding a classic Pontiac, or addressing persistent oil weeps around the valve cover perimeter, quality gasket replacement is essential to engine longevity and cleanliness.

SCE Gaskets manufactures these 5/16 Pontiac valve cover gaskets using proven elastomer and cork-composite materials that withstand sustained engine heat and oil exposure without degradation. The gasket profile is precision-engineered to match Pontiac valve cover flange geometry, ensuring uniform compression across all fastening points and eliminating pinch-points that can lead to premature failure. At 0.55 lbs and measuring 24 inches in length, this gasket set provides complete coverage for standard Pontiac small-block and mid-block applications, with exact port hole alignment to prevent bypass leakage.

Technicians and Pontiac enthusiasts benefit most from this gasket during valve cover removal for spark plug access, PCV system service, or rocker arm inspection. Installation requires only hand-torquing fasteners to specification—no sealant is necessary when using quality gasket material. This product is compatible with Pontiac engines featuring 5/16-inch valve cover fastener patterns across generation years, making it an economical solution for stopping oil seepage and restoring a clean engine bay.
