Valve Cover Gasket (1)

The Valve Cover Gasket for Small Block Chevy engines is a critical OEM-specification replacement component designed to seal the interface between the valve cover and cylinder head. This gasket prevents oil leakage from the engine's top end, protecting internal engine components and maintaining proper crankcase ventilation. Engineered by Chevrolet Performance, this single gasket is essential for any Small Block rebuild, restoration, or routine maintenance on Chevy performance platforms.

Constructed from durable rubber material with a precision thickness of 0.177 inches, this valve cover gasket provides reliable compression and flex to maintain an effective seal across varying engine temperatures and vibration cycles. The gasket's engineered profile conforms to the valve cover mounting surface, eliminating gaps that would allow oil seepage. Chevrolet Performance's OEM-grade construction ensures the gasket withstands thermal cycling and mechanical stress without hardening or losing elasticity over extended service intervals.

This gasket is ideal for Small Block Chevy engine owners performing top-end service, head gasket replacement, or complete engine rebuilds where valve cover removal is necessary. Installation is straightforward: remove the old gasket, clean the mounting surfaces thoroughly, and install the new gasket to ensure a leak-free seal. Each package contains one gasket (MPN 10046089), sufficient for one valve cover installation on a standard Small Block Chevy platform.
