Engine cylinder head leaking is a common problem, so can we solve the problem? The answer will be revealed to you below.

First of all, it should be clear that if the leaking area of the engine cylinder head is not extensive, it is entirely possible to repair it. The specific repair method is as follows:

1. If the leak occurs at the joint between the cylinder block and the cylinder head, this usually means that the cylinder block gasket is leaking (that is, the cylinder gasket is damaged).

2. If there is a leak in other parts of the cylinder head, it may be due to bubbles (often called sand eyes) generated inside the cylinder head during the casting process, which causes the cylinder head to leak.

3. For different causes of leaks, we need to take different solutions. For leaks at the joint between the cylinder block and the cylinder head, we should replace the new cylinder gasket immediately. For leaks in other parts of the cylinder head (such as sand eyes), you should contact the manufacturer for compensation or replace a new cylinder head body for free.

In summary, the problem of water leakage in the engine cylinder head can be effectively repaired, but the specific repair method depends on the actual situation. Once the cylinder head is found to be leaking, it is recommended to repair it as soon as possible to avoid adverse effects on the normal use of the vehicle.
