The Isuzu head gasket forms one of the toughest seals in the engine, designed to contain the intense pressure and heat of engine combustion within the combustion chambers. By forming a tight seal between the cylinder head and the engine block, the Isuzu head gasket seals the passages that carry oil and engine coolant between these two components as well as the combustion chambers, protecting against the damage the intense pressure and heat could cause to sensitive vehicle parts if allowed to escape. The seal formed by the Isuzu head gasket also helps to protect the efficiency of the engine and the cooling system, preventing the coolant from leaking into the engine oil, or the oil from leaching into the cooling system. The Isuzu head gasket is designed to withstand the forces of engine combustion and exposure to vehicle fluids and the chemicals they contain throughout the life of the engine, but under certain conditions the seal can fail prematurely. Engine overheating is a leading reason for failure of the Isuzu head gasket seal, the extreme heat causing the cylinder head to swell or warp, crushing the gasket to breach the seal. Detonation in the combustion chambers can cause damage to the combustion armor, leaving the Isuzu head gasket unprotected from the intense pressure and heat produced by the combustion process. This can wear away at the Isuzu head gasket, allowing it to leak. We carry a selection of quality Isuzu head gasket replacements in our user-friendly online catalog.
