Product Description
Genuine GM Oil Pan Port Seal – GM 12621086
OEM Oil Pan Port Seal | Fits 2014+ Gen V LT-Based V8 Engines
This Genuine GM oil pan port seal (Part #12621086) is a critical OEM sealing component used on Gen V LT-based V8 engines. Located on top of the oil pan above the oil filter area, this seal helps maintain proper oil pressure while preventing leaks that can develop as seals age and harden over time.
Anytime the oil pan is removed—especially on higher-mileage engines—these seals should be replaced to ensure long-term reliability and proper lubrication. Using OEM GM seals guarantees correct fitment, material quality, and sealing performance. Two (2) seals are required per engine.
