What Causes The Cracks In The Engine Cylinder Head?

The cracks in the engine cylinder head may be caused by the following factors:

1. Poor heat dissipation or long-term operation in a high temperature environment may cause the cylinder head to crack. The strength and toughness of metals will be reduced at high temperatures. Therefore, if the engine's cooling system performs poorly and the cylinder head is kept at a high temperature, cracks may occur.

2. The cylinder head is hit or impacted by external forces, which is also a possible cause of cracking. When the vehicle encounters an accident or collision while driving, the engine cylinder head may crack due to external forces.

3. The manufacturing problems of the cylinder head itself, such as defects such as pores and sand holes in the casting process, may also cause it to crack. These defects will weaken the strength and durability of the cylinder head, making it more prone to cracks during use.

The exact cause needs to be judged based on the actual situation. It is recommended that you send the vehicle to a professional repair station for detailed inspection and repair.
