Intake Valley Pan Gasket GM LS Engines 05-11

The Intake Valley Pan Gasket GM LS Engines 05-11 by FEL-PRO is an OEM-quality replacement gasket designed for sealing the critical junction between the engine block and intake manifold on fifth and sixth-generation LS-platform engines. This gasket is essential for both modified and stock LS builds, addressing common oil seepage issues.

Constructed from a composite material, this gasket is engineered to withstand the thermal cycling and pressure dynamics found in the LS valley, where coolant, oil, and intake heat converge. Its precise geometry ensures a perfect fit along the 24-inch valley pan perimeter, with strategically positioned sealing surfaces that prevent oil weeping and coolant intrusion.

This gasket is particularly beneficial for LS engine owners dealing with persistent valley leaks, a common issue in 2005–2011 LS2, LS3, LS7, and LS9 applications. Installation requires the removal of the intake manifold and careful cleaning of the valley pan and block to ensure optimal performance.
