Seals the crankshaft at the engine block and cover interfaces to maintain proper oil containment and prevent external leakage. Designed to withstand normal engine operating temperatures, crankshaft rotational speeds, and internal crankcase pressure fluctuations encountered in GM engine applications. This GM Genuine Part is engineered, validated, and manufactured to meet General Motors OE material, dimensional, and durability specifications. OE components are designed to integrate correctly with GM engine sealing surfaces and tolerances; some aftermarket replacements may not match OE sealing performance or longevity depending on the application.
Applications: GM gasoline engines including 4.3L V6, 5.3L V8, 6.2L V8 (naturally aspirated, non-supercharged, non-ZR1), and 6.6L gasoline V8 platforms.
