Pontiac V.C. Gaskets

The Pontiac V.C. Gaskets (SKU MRG5869) are a direct-fit valve cover gasket pair designed for Pontiac V8 engines. These gaskets feature Ultra-Seal construction with a rubber-coated cork core measuring 0.187 inches thick, engineered to prevent oil weeping and maintain a reliable seal under normal engine operating temperatures and pressures. Valve cover gaskets are a critical engine sealing component; failure results in oil seepage, potential contamination of spark plug wells, and eventual loss of engine oil if left unaddressed.

The rubber-coated cork construction balances compliance and durability—cork provides conformability to casting irregularities common in older Pontiac engine heads, while the rubber coating adds tensile strength and resistance to oil degradation. The 0.187-inch thickness is precisely matched to Pontiac V8 valve cover dimensions, ensuring proper clamp load distribution without over-compression. This gasket pair replaces both driver and passenger side valve covers, making it a complete solution for addressing leaks on dual-cover V8 applications. Installation requires only standard hand tools and basic mechanical knowledge, with gaskets seated in recessed grooves that center them during reassembly.

Pontiac V8 owners—whether maintaining classic muscle cars, daily-driver Bonnevilles, or high-performance variants—encounter valve cover seepage as engines accumulate miles. Cork-based gaskets have long been the standard for these applications due to their proven compatibility with Pontiac head casting surfaces and availability of accurate replacement specifications. This gasket pair addresses that maintenance need directly, restoring a dry engine compartment and preventing oil drips that complicate diagnostics and attract debris.
