The engine block can be said to act as a brain of the engine and has the function of regulating temperature. Therefore, when it breaks, it naturally needs to be repaired in time. So, how to repair a broken engine block, let's give you a detailed repair method.

Repair method for broken engine block:
1. First of all, sand out the rust around the cracks of the cylinder block with coarse sandpaper. When it is polished to a certain level, we can find the cracked end.
2. Then, just proceed to the welding patching machine directly. But pay attention to the warpage phenomenon of the welding part. If there is any, be sure to hit the solder joint while it is hot to avoid leaving some solder slag on it.
3. After the patch is completed, we also need to pad the patch plate and the cylinder block (cylinder head) with a layer of asbestos pad, and then apply a layer of lubricating oil on both sides.
It is worth mentioning that whether the engine block can be repaired or not depends on the actual situation. First of all, if it is a dry or wet engine block, it is generally difficult to repair. After all, the cylinder liner of this cylinder block is very thin, so it can only be replaced with a new cylinder block. If it is a wet engine block and the crack is relatively small, we can bore the cylinder and replace the cylinder liner, but the situation is serious and must be replaced with a new cylinder block.
Secondly, we also need to see where the crack is. If it is in the middle of the engine, we just need to repair it according to the above-mentioned method, but if it is actually at the cylinder head of the engine, it will be a bit old. Only replace the engine block with a new one.
