Design Philosophy

Oil-resistant rubber gasket designed for 4HG1-T engines. Precision-molded to seal the valve chamber cover, preventing engine oil leakage and keeping contaminants out of the valve train under high-temperature operating conditions.

How It Works

Installed between the valve chamber cover and the cylinder head. The rubber gasket compresses under bolt torque to fill surface imperfections, creating a reliable oil-tight seal that withstands vibration and thermal cycling.

Problems It Solves

Fixes oil leaks from the valve chamber cover caused by hardened, cracked, or aged gaskets. Restores proper sealing, keeps the engine top clean, and prevents oil contamination in NPR / NQR trucks.
