How to pull the engine when there is enough oil and water?

1. The engine cooling system failed to be replenished in time due to water leakage, resulting in overheating of the engine;

2. The piston ring breaks and scratches the cylinder wall;

3. The piston pin circlip falls off and scratches the cylinder wall;

4. The piston ring is stuck in the ring groove due to carbon deposition and loses its sealing function;

5. The piston pin comes out and scratches the cylinder wall;

6. Foreign matter enters the cylinder;

7. The clearance between piston and cylinder wall is too small;

8. The piston pin is assembled too tightly, resulting in the deformation of the piston;

9, the piston thermal deformation is serious or burn top melting;

10, long-term high-speed or overload operation of the engine, etc.

Landlord, the above are the reasons for pulling the cylinder. Not only the lack of oil and coolant, but also the common cause of cylinder pulling is that foreign objects enter the cylinder, which is more common for those who never wash the throttle and don't know how to wash it.
