Wei Jun waste gas valve pipeline leaks oil.

The wear between the valve guide and the valve stem can be very serious.

Waste gas valve, also known as oil-gas separator, is used to separate engine oil from crankcase waste gas to reduce the discharge of engine oil from crankcase breathing port to the outside of the engine. The reason for the oil leakage of the waste gas valve may be the serious wear between the valve guide and the valve stem, which leads to the excessive clearance and the downward escape of the oil. The solution is to find the damaged place and replace it.
