Cylinder head gasket leaks

Fault manifestations: engine overheating, power loss, exhaust pipe smoke, coolant or oil mixing, etc.

Repair method:

Check whether the gasket is damaged or aged.

Clean the contact surface between the cylinder head and the cylinder block to ensure it is flat and scratch-free.

Replace a Strong sealing cylinder head gasket to ensure sealing.

Use an appropriate torque tool to tighten the cylinder head bolts evenly in the specified order.

Cylinder head gasket burns

Fault manifestation: The engine temperature is too high, and the engine has a serious power drop or abnormal noise.

Repair method:

Check whether the cylinder head has cracks or deformations, and repair it if necessary.

Replace the burned cylinder head gasket.

Confirm that the cooling system is working properly to avoid overheating.

Cylinder head gasket is deformed or aged

Fault manifestation: engine coolant or oil leakage.

Repair method:

Replace the aged or deformed cylinder head gasket.

Check and make sure there is no obvious damage to the contact surface between the cylinder head and the cylinder block.

Use high-quality, high-temperature resistant gasket materials to enhance sealing.

Poor sealing of cylinder head gasket

Fault manifestation: The engine oil and coolant are mixed, and the coolant level drops abnormally.

Repair method:

Thoroughly clean the contact surface between the cylinder head and the cylinder block to ensure there are no impurities.

Ensure that the cylinder head gasket is installed correctly to avoid sealing failure due to improper installation.

Check the tightness of the cylinder head bolts and adjust the tightening torque if necessary.

Premature damage to the cylinder head gasket

Fault manifestation: The engine has excessive cooling system pressure or overheating.

Repair method:

Use a high-quality cylinder head gasket suitable for the engine.

Check the engine’s cooling system and coolant quality to avoid damage to the cylinder head gasket due to poor cooling.

Replace the cylinder head gasket at the interval recommended by the manufacturer to avoid excessive wear.

Damaged cylinder head gasket

Fault manifestation: The engine has obvious exhaust abnormalities, engine power decreases, and there may be obvious cracks or breaks in the cylinder head gasket.

Repair method:

Replace the damaged cylinder head gasket and check whether the cylinder head and cylinder block are damaged. If there is damage, repair or replace the cylinder head.

Ensure that the new gasket is installed evenly to avoid damage to the new gasket.

The failure of the engine cylinder head gasket usually manifests as leakage, overheating, ablation or deformation, which affects the normal operation of the engine.

The key to solving these problems is to find the cause of the failure in time and take appropriate repair measures, such as replacing the gasket, repairing the contact surface, checking the cooling system, etc. Ensuring the sealing performance of the cylinder head gasket is the basis for the smooth operation of the engine.
