Valve Cover Gasket LS 1997 - Up Rubber

The Valve Cover Gasket LS 1997-Up Rubber from Straub Technologies Inc. is a direct-fit replacement gasket engineered for GM LS-series engines manufactured from 1997 onward. This rubber gasket seals the critical interface between the valve cover and cylinder head, preventing oil leakage that can compromise engine bay cleanliness and lead to costly cleanup or component damage. For operators and enthusiasts maintaining LS-powered vehicles—whether in tactical fleet operations, personal rigs, or high-performance builds—a reliable valve cover gasket is foundational maintenance.

This gasket measures 5.25 x 0.85 x 6.8 inches and weighs just 0.1 lbs, making it a lightweight, direct replacement part for the LS valve cover assembly. The rubber composition provides excellent oil resistance and thermal stability across the operating temperature range typical of LS engines, which generate sustained heat under load. The gasket's design ensures a tight seal without requiring excessive torque on cover bolts, reducing the risk of over-tightening and thread damage—a common field concern during maintenance cycles.

This replacement is suitable for anyone maintaining 1997-and-later LS-platform engines, including fleet mechanics, independent technicians, and DIY builders who need OEM-specification gaskets for routine service. Whether replacing a hardened or degraded gasket during scheduled maintenance or emergency repair in the field, this Straub Technologies LS valve cover gasket delivers verified fitment and proven sealing performance. Part number 346-7683 is the specification reference for inventory and compatibility confirmation across LS engine variants.
