Does Removing the Cylinder Head Count as Engine Disassembly?

[FrankAnn]

Removing the cylinder head counts as engine disassembly. Below is an introduction to the causes of engine cylinder head damage: 1. Elongation or loosening of cylinder head bolts and nuts: The elongation or loosening of cylinder head bolts and nuts can result in insufficient pressure and uneven pressure distribution on the joint surface between the cylinder head and the engine block, leading to high-temperature and high-pressure gases escaping from areas with lower pressure and burning the cylinder head gasket. 2. Deformation of the joint surface between the cylinder head and the engine block: Deformation of the joint surface between the cylinder head and the engine block prevents the cylinder head gasket from being evenly compressed, causing gas leakage and resulting in gasket burn-out. 3. Improper installation: During installation, if the joint surface of the cylinder head gasket is not clean, if the cylinder head bolts and nuts are tightened in the wrong sequence, if the torque is insufficient or uneven, or if the height of the upper end face of each cylinder liner above the engine block's upper plane is insufficient or uneven, gas leakage can occur, leading to gasket burn-out. 4. Engine overheating: High temperatures can cause the cylinder head gasket to lose its original elasticity and become brittle, eventually burning out. 5. Poor quality of the gasket itself: Uneven thickness, uneven rolled edges, insufficient elasticity, inferior material, uneven surface, or damage to the gasket during disassembly and assembly can all easily lead to cylinder head gasket burn-out.
