Pontiac V.C. Gasket

The Pontiac V.C. Gasket from Mr. Gasket is a precision valve cover gasket engineered for Pontiac V8 engines, supplied as a matched pair to address both cylinder head covers in a single installation. This gasket exists because valve cover sealing is critical to engine health—oil leaks from deteriorated factory gaskets lead to contamination of spark plugs, ignition components, and engine bay corrosion. Whether you're restoring a classic Pontiac muscle car, refreshing an engine after decades of service, or addressing a slow weep from aging original equipment, this replacement gasket delivers the seal integrity modern enthusiasts and mechanics demand.

Constructed from a cork and rubber composite material at 0.187 inches thick, the Pontiac V.C. Gasket combines the conformability of cork with the durability and oil resistance of synthetic rubber. This hybrid composition handles the thermal cycling and pressure variations typical of V8 combustion chambers while resisting oil degradation better than pure cork alone. The gasket's precise thickness ensures proper sealing pressure against valve cover flanges without over-compression that would compromise the seal over time. Mr. Gasket's manufacturing tolerances guarantee fitment on OEM valve cover mounting surfaces, eliminating the guesswork and leak risk associated with inferior or undersized alternatives.

Mechanics and enthusiasts working on Pontiac V8 applications—from 400-cubic-inch street engines to 455 big-blocks—benefit most from this gasket pair because it eliminates the need for separate sourcing and ensures symmetrical sealing across both covers. Installation is straightforward: remove the old gasket residue, position the new gasket on the valve cover flange, reinstall the cover with correct bolt torque sequence, and verify no leaks after warm-up. The pair format saves labor time and ensures your engine runs clean without oil seepage onto headers, exhaust manifolds, or engine bay wiring. For restoration projects, daily drivers, and performance builds alike, this gasket delivers reliable, long-term valve cover sealing.
