The engine cylinder head is broken, can it be repaired?

2023-11-24

Yes, but it depends on the damage.
There are two repair methods: welding repair or direct replacement.
There are many reasons for cylinder head damage, such as when alloy cylinder heads encounter high temperatures; When the tightening torque of the cylinder head bolts is uneven; When the cylinder gasket is extensively eroded; And other external forces can cause deformation of the cylinder head.
Cylinder head fracture is a common problem, mainly manifested in the following points:
1.When driving, I often feel that the engine is weak and it is difficult to accelerate. Leakage at the connection between the cylinder head and cylinder block or locally;
2.After the engine starts, one or two cylinders do not work and make a "bang, bang" sound. The radiator is continuously lacking water, with bubbles appearing at the radiator inlet or oil droplets on the surface of the cooling water;
3.Pull out the dipstick to check the oil. The oil is milky white. Water droplets continuously flow out of the exhaust pipe;
4. The engine water temperature is too high. When the cylinder gasket is severely damaged, not only does the engine power decrease severely, but sometimes it even cannot be started.

Generally, if such a malfunction occurs, the cylinder can be replaced, and the oil will be smoother.
