Does a Blown Cylinder Head Gasket Require an Overhaul?
1 Answers
An engine's blown cylinder head gasket does not require an overhaul; replacing the gasket is sufficient. Changing the cylinder head gasket is not considered an engine overhaul but rather a medium repair, and it has minimal impact on the engine. Function of the Cylinder Head Gasket: The cylinder head gasket, also known as the cylinder gasket, is located between the cylinder head and the cylinder block. Its function is to fill the microscopic gaps between the cylinder block and the cylinder head, ensuring a good seal at the joint surface, thereby maintaining the sealing of the combustion chamber and preventing gas leakage from the cylinder and coolant leakage from the water jacket. Classification of Cylinder Head Gaskets: Depending on the material, cylinder head gaskets can be divided into several types, including metal-asbestos gaskets, metal-composite gaskets, and all-metal gaskets.
