Valve Cover Grommet Set 97-16 Chevy LS

The Valve Cover Grommet Set 97-16 Chevy LS is a crucial component for anyone maintaining or rebuilding an LS-platform engine. These grommets are essential for preventing oil leaks around spark plug wire tubes and sensor passages where the valve cover meets the cylinder head. If you notice oil weeping around your valve covers on a 1997–2016 Chevy LS engine, worn or deteriorated grommets are likely the cause, making replacement a necessary part of engine upkeep.

Manufactured under part number GS33466, this grommet set features engineered elastomer construction designed to withstand high under-hood temperatures and thermal cycling typical of LS engines. The grommets compress against the valve cover gasket surface to create a reliable seal while accommodating minor movement and vibration from engine operation. Using OEM-equivalent materials ensures that the grommets maintain their compression characteristics over time, unlike inferior aftermarket options that may harden and lose sealing ability.

This grommet set is suitable for various LS engine applications, including LS1, LS2, LS3, LS6, LSx, and truck variants like the 5.3L and 6.0L. Whether you're performing routine maintenance on a stock engine or building a modified LS for a project vehicle, replacing the grommets during valve cover service is essential for preventing future oil leaks and ensuring optimal engine performance.
