Spring Action of BMW x5 Waste Gas Valve

Thereby adjusting the negative pressure.

The broken waste gas valve will cause the vehicle to shake and give an error, and the engine oil will whistle. The valve cover of BMW engine is integrated, and the waste gas valve is a very easy thing to break, and the rubber film inside is very easy to break after a long time.

Generally, it is best to replace the waste gas valve once every six years: 1. It is best to replace the oil-gas separator in time after cleaning the carbon deposit by hanging the 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 entering 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. Because 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.
