Does replacing the cylinder head gasket on a Teana V6 require engine removal?

[Tami]

Replacing the cylinder head gasket does not require removing the entire engine; it only necessitates removing the cylinder head. Function of the cylinder head gasket: The cylinder head gasket is a sealing component between the engine block's top surface and the cylinder head's bottom surface. Its role is to maintain cylinder sealing to prevent gas leakage and to ensure that coolant and engine oil flowing from the engine block to the cylinder head do not leak. The cylinder head gasket withstands the pressure from tightening the cylinder head bolts and is subjected to the high temperature and pressure of combustion gases inside the cylinder, as well as corrosion from engine oil and coolant. Requirements for the cylinder head gasket: The cylinder head gasket must have sufficient strength and be resistant to pressure, heat, and corrosion. Additionally, it needs to possess a certain degree of elasticity to compensate for the roughness and unevenness of the engine block's top surface and the cylinder head's bottom surface, as well as the deformation of the cylinder head caused by gas forces during engine operation.
