Replace the rear engine cover oil-gallery seal on compatible Gen V GM V8 engines with this OEM-quality alternative from Michigan Motorsports. Designed to replace GM part number 12627520, this seal installs in the rear engine cover and seals the crossover passage connecting the engine’s two lifter oil galleries.
Key Features & Benefits
- Replaces GM Part Number 12627520: Provides an OEM-quality Michigan Motorsports alternative for applications originally equipped with GM rear-cover oil-gallery seal 12627520. The direct replacement positioning helps identify the correct seal for compatible Gen V LT-based gasoline V8 engines.
- Rear Engine Cover Application: Designed for the oil-gallery crossover passage located at the rear engine cover. This application-specific seal fits between the corresponding rear-cover passages rather than serving as the perimeter gasket or rear crankshaft seal.
- Seals the Lifter Oil-Gallery Crossover: This seal is used where the rear engine cover connects the engine’s two lifter oil galleries. Its purpose and location match the specialized crossover seal used in compatible Gen V GM V8 engine assemblies.
- Broad Gen V LT Engine Coverage: Fits the supplied 2014 and newer LT1, LT4, L83, L84, L86, L87, L82, L8T and L8B engine applications. Coverage includes compatible 5.3L, 6.2L and 6.6L gasoline V8 configurations.
- Extensive GM Vehicle Compatibility: Applications include select Cadillac, Chevrolet and GMC cars, trucks, SUVs, vans and commercial vehicles. Compatible models range from performance applications such as the Camaro, Corvette, CT5 and CTS-V to Silverado, Sierra, Tahoe, Yukon, Express and Savana platforms.
