326-455 Pontiac V/C Gskt 1/4in Thick Cork/Rubber

The 326-455 Pontiac V/C Gskt 1/4in Thick Cork/Rubber valve cover gasket by FEL-PRO is engineered to seal the valve cover assembly on Pontiac V8 engines, preventing oil leakage and contamination of the combustion chamber. Valve cover gaskets are critical wear items that deteriorate over time due to exposure to heat cycles, engine vibration, and oil breakdown. This pair of gaskets addresses the common problem of slow oil seepage around the valve cover perimeter, a condition that worsens with age and can lead to spark plug fouling, rough idle, and potential engine damage if left unaddressed.

This gasket features a 1/4-inch (0.250-inch) thickness cork and rubber composite construction, a proven material combination that balances resilience and compressibility to create a reliable seal under varying engine temperatures and pressures. The cork core provides excellent oil resistance and maintains flexibility across the operating range of classic Pontiac V8 powerplants, while the rubber perimeter offers durability against vibration and thermal cycling. The gasket's dimensional profile is precisely matched to OEM specifications for Pontiac 326 and 455 cubic-inch V8 engines, ensuring proper seating on the valve cover flange and preventing blowby or leakage at the combustion chamber edge.

Technicians and restoration enthusiasts working on classic Pontiac muscle cars, daily drivers, and performance builds benefit most from this OEM-equivalent gasket set. Installation is straightforward: the old gasket is removed, the valve cover surface is cleaned to bare metal, and the new gasket is positioned and torqued to specification. This pair covers both valve covers on a V8 engine, making it an economical solution for a complete seal refresh. Compatibility is confirmed for Pontiac 326 and 455 V8 engines; always verify your specific engine code and year before purchase to ensure proper fit and sealing performance.
