8-98114256-0 8981142560 Cylinder Head Gasket for Isuzu 4HK1 ZX200-3 ZX240-3

The cylinder gasket withstands the pressure caused by tightening the cylinder head bolts, and is subject to the high temperature and pressure of the combustion gases in the cylinder, as well as corrosion from the engine oil and coolant.

The cylinder gasket is the seal between the top surface of the engine block and the bottom surface of the cylinder head. Its function is to keep the cylinder seal from leaking and to keep the coolant and oil flowing from the body to the cylinder head from leaking.

The cylinder gasket should be strong enough and resistant to pressure, heat and corrosion. In addition, a certain degree of elasticity is needed to compensate for the roughness and unevenness of the top surface of the body and the bottom surface of the cylinder head, as well as the deformation of the cylinder head due to gas forces when the engine is operating.
