Product Description
Michigan Motorsports Oil Pan Port Seal (Pair) – Replaces GM 12621086
Fits 2014–Newer GM Gen V LT 5.3L, 6.2L & 6.6L Gasoline V8 Engines (LT1, LT4, L83, L84, L86, L87, L8T, L82, L8B)
The Michigan Motorsports Oil Pan Port Seal set is a direct replacement solution for common oil leaks on GM Gen V LT-based V8 engines. These seals are located on top of the oil pan above the oil filter area and play a critical role in maintaining proper oil pressure and preventing leaks. Over time, factory seals can harden—especially on higher mileage engines—making replacement essential anytime the oil pan is removed. This listing includes two high-quality replacement seals designed to meet or exceed OEM fit and sealing performance.
