Miscellaneous Engine

Browse New OEM miscellaneous engine components for GM vehicles. Our inventory covers valve covers, timing cover components, engine gaskets, O-rings, oil separator assemblies, and specialty engine hardware — all factory-original parts sourced from GM surplus.

Engine accessory and sealing components must match the exact mating surface profiles and material specifications of your engine. OEM gaskets use the correct fiber composition and surface coating for your engine's operating temperature and coolant chemistry. OEM valve covers are cast or formed to the exact port and PCV system integration of your specific engine.

Verify part numbers against your engine's RPO code and casting numbers before ordering. Contact us for assistance identifying specific engine components.
