Intake Valley Pan Gasket GM LS Engines 05-11

The Intake Valley Pan Gasket GM LS Engines 05-11 is a factory-specification replacement gasket designed for General Motors LS-series V8 engines spanning 2005–2011 model years. Built by FEL-PRO, a trusted OEM gasket manufacturer with decades of engine sealing expertise, this valley cover gasket eliminates coolant and oil seepage at the intake manifold valley—a critical sealing point that directly impacts engine longevity. Whether you're performing routine maintenance on a performance truck, restoring a classic LS platform, or rebuilding after high-mileage wear, this gasket ensures a factory-correct seal without compromise.

This gasket features a 0.125-inch thickness with a composite construction combining aluminum and rubber materials—a proven design that withstands the thermal cycling and pressure cycles inherent to LS engine operation. The aluminum carrier provides structural rigidity and heat dissipation, while the rubber-faced sealing surfaces conform to machined surfaces on the block and intake valley cover, preventing fluid weeping under both idle and high-load conditions. Proper installation with factory torque specifications ensures the gasket seats uniformly across its full surface area, maximizing seal integrity and engine bay cleanliness.

Technicians and LS engine enthusiasts benefit most from this gasket when addressing visible coolant or oil residue around the valley cover area or as preventive replacement during intake manifold service. Installation is straightforward for anyone with basic mechanical skill—remove the intake manifold, clean both mating surfaces thoroughly, install the new gasket, and reinstall with even, sequenced bolt torque. Compatible with all 2005–2011 LS-series engines across Chevrolet, GMC, Cadillac, and Pontiac platforms, this OEM-specification component restores factory sealing performance and is the preferred choice for shops and DIY builders seeking long-term reliability without aftermarket experimentation.
