Timing Cover Seal LT Gen-V

The Timing Cover Seal LT Gen-V from Chevrolet Performance is an essential OEM replacement gasket engineered for modern LS-family V8 engines, particularly the LT-series platform found in fifth-generation Camaros, Corvettes, and Silverado trucks. This precision component seals the critical interface between the engine block and timing cover, preventing oil seepage that compromises engine cleanliness and long-term reliability. Whether you're performing routine maintenance, recovering from a timing cover removal, or rebuilding a high-performance engine, a factory-correct seal ensures your power plant remains leak-free and operating at peak efficiency.

This OEM Chevrolet Performance gasket is manufactured to exacting tolerances and engineered with premium elastomer compound designed to withstand sustained heat cycling, oil chemistry, and the vibration inherent to high-output engine platforms. The seal's geometry precisely matches the timing cover mounting surface, ensuring positive compression and zero-leak sealing across the full operating temperature range. At just 0.05 lbs and measuring 3.4 x 0.5 x 3.4 inches, this compact component delivers critical functionality without added weight, making it the correct choice for stock restorations and performance builds alike where OEM integrity is non-negotiable.

Technicians and engine builders depend on this Timing Cover Seal LT Gen-V when servicing LT Gen-V engines—including 5.3L, 6.2L, and 6.6L variants across Corvette C8, Camaro SS, Silverado, and aftermarket applications. Installation requires only basic hand tools and mild solvent cleaning of the mating surfaces; proper torque sequence on the timing cover fasteners ensures repeatable seal compression. Using the genuine Chevrolet Performance part (MPN 12634614) eliminates compatibility guesswork and warranty concerns, protecting your investment in engine longevity whether your build prioritizes stock reliability or enhanced output.
