Seal - Oil Pan High Pressure Port Gen-V LT

The Seal - Oil Pan High Pressure Port Gen-V LT from Chevrolet Performance is a factory OEM replacement seal engineered for GM's fifth-generation LT-series engines. This component serves a critical role in maintaining oil system integrity at the high-pressure port located at the rear of the oil pan. Engine builders, performance technicians, and serious enthusiasts rely on this seal to prevent costly oil seepage and system pressure loss during engine assembly, rebuild, or maintenance work.

Designed specifically for the Gen-V LT engine architecture, this oil pan port seal functions as a static gasket interface, blocking oil leakage at the high-pressure gallery connection point. The seal's compact 2.2 x 1 x 4.25-inch profile and minimal weight of 0.01 lbs indicate a precision-molded elastomer or composite construction optimized for the OEM port geometry. Proper sealing at this junction is essential—failure here can result in oil starvation to critical engine components and elevated operating temperatures, which directly impacts engine longevity and performance under load.

This replacement seal is mandatory for anyone performing a full oil pan gasket service, engine teardown, or aftermarket oil system modifications on Gen-V LT-powered vehicles. Whether rebuilding a LS-swapped project, servicing a factory LT engine, or upgrading to high-capacity oil pans, retaining the original OEM seal specification ensures leak-free operation and maintains pressure delivery to the engine's lubrication network. Installation is straightforward during oil pan removal, and using Chevrolet Performance's genuine component eliminates guesswork regarding fitment and material durability.
