How to Determine if the Cylinder Head Gasket is Blown?

[DelLane]

Methods to determine if the cylinder head gasket is blown: 1. Overheating; 2. No water leakage but water shortage; 3. Water mixing in the radiator, with rattling noises from the engine cylinders; 4. Deformation, elongation, or loosening of cylinder head bolts and nuts. When nuts or bolts loosen, the pressure on the joint surface becomes uneven, and high-pressure, high-temperature gases along with rapidly flowing coolant and lubricating oil continuously erode the cylinder head gasket, leading to gasket failure; 5. Abnormal operation of the engine cooling system, causing the engine to operate at high temperatures for extended periods, resulting in excessive heat exposure to the cylinder head gasket, loss of elasticity, and eventual erosion, leading to gasket damage and failure; 6. Use of substandard materials when selecting the cylinder head gasket; 7. Deformation of the joint surface between the cylinder block and cylinder head, causing the cylinder head gasket to be unevenly compressed, leading to air leakage and gasket burn-out; 8. Improper driving techniques, such as frequently slamming the accelerator, sudden acceleration, and high-speed operation, which increase pressure and accelerate gasket erosion.
