Common causes of oil leakage of a cylinder head:

Aging or damage of the cylinder head gasket: The cylinder head gasket serves the main purpose of sealing the joint between the cylinder head and the cylinder body. If the gasket loses its sealing effect due to high temperature, aging, or chemical corrosion, oil leakage will occur.

Deformation or cracking of the cylinder head: If the cylinder head deforms or cracks due to overheating or excessive pressure, oil leakage may occur.

Loose fastening bolt: If the fastening bolt of the cylinder head has loosened due to frequent vibration, the sealing between the cylinder head and the cylinder body will become weaker, leading to oil leakage.

Use of inappropriate engine oil: If inappropriate engine oil is used (such as oil with a viscosity level not in line with engine requirement), it may also impair sealing performance and result in oil leakage.

Cooling system failure: A cooling system failure can cause excessive temperature in the cylinder head, and consequently lead to fatigue and damage to the cylinder head.

Normal wear: After long use of the engine, friction and wear of the cylinder head and other components can also cause oil leakage.
