The exhaust valve of Toyota VIOS engine is broken. Can I replace it at home?

Specific steps:

1. It is best to replace the oil-gas separator in time after using the carbon deposit cleaning agent, especially after cleaning the carbon deposit with a "hanging bottle".

2. When the oil consumption suddenly increases, the oil-gas separator should also be replaced in time. Because the main function of the oil-gas separator is to separate the fuel vapor and engine oil escaping into the crankcase, the oil-gas separator is also called the waste gas valve.

3. If the engine oil is damaged, it will enter the combustion chamber with the fuel vapor, resulting in an increase in engine oil consumption, that is, burning engine oil.

4. As the core component of the oil-gas separator is the leather cup, with the extension of service time, the elasticity of the leather cup will become worse and the separation effect will decrease. Generally, the life of rubber parts is less than 6 years. Therefore, even if there is no abnormality, it is recommended to replace the oil-gas separator every six years.
