Bora EA 1 1 1 Waste gas valve leaks oil.

Find the damaged place and replace it.

Bora EA 1 1 1 It is abnormal that there is slight oil in the waste gas valve pipe. The reason for the leakage of waste gas valve may be that the valve guide and valve stem are seriously worn and the gap is too large, which makes the oil flow down. The solution is to find the damaged place and replace it.

It is also possible that there is something wrong with the waste gas valve, which is generally installed near the valve cover, with one side connected to the throttle inlet hose and the other side connected to the valve cover. When it has problems, it will lose the function of oil-gas separation, and at the same time, it will suck in engine oil, so that the waste gas valve pipe has engine oil. In this case, the oil-gas separator can be replaced.
