The LS Timing Cover Gasket 1997-Up from Straub Technologies Inc. is an essential engine seal designed for Gen III, Gen IV, and Gen V LS-platform engines spanning nearly three decades of production. Whether you're rebuilding a carbureted 5.3L in a square-body Chevy or refreshing the timing cover on a modern LT1, this gasket prevents coolant and oil seepage at the front of the engine where the timing cover meets the block. Timing cover leaks are among the most common issues on high-mileage LS builds, making this OEM-quality replacement gasket a critical component for any serious engine work or restoration project.
This gasket seals the interface between the timing cover and engine block, a high-pressure zone exposed to both oil and coolant galleries. The material composition resists heat cycling and maintains elasticity across the broad operating temperature range typical of street and competition LS engines. Proper installation requires a clean sealing surface on both the cover and block—any debris or old gasket material will compromise the seal, leading to weeping or outright leaks. Straub Technologies' manufacturing tolerances ensure consistent fit across all LS variants, eliminating the guesswork often encountered with aftermarket alternatives.
Rebuilders, restorations specialists, and performance shops trust this gasket for everything from stock replacements to turbocharged stroker builds. Its compatibility spans 1997-and-later LS applications—covering the early LS1 through today's Gen V engines—making it a must-have for engine swaps and long-block assembly. During timing cover installation, apply a light bead of RTV around the perimeter and torque the fasteners in a cross pattern to OEM specifications to ensure maximum seal integrity. Whether you're servicing an original engine or supporting a full rebuild, this Straub Technologies gasket delivers the reliability and longevity that serious builders demand.
