How to judge the exhaust valve of Elysee?

Judgement method of Elysee exhaust valve;

1, put the dipstick in the throttle, and then take it out for inspection. If there is only some putty on the fuel gauge, there is no problem, but if there is oil, it proves that the waste gas valve has been damaged.

2. Start the engine, let it run at idle speed, then pump air and directly vacuum the diaphragm chamber of exhaust gas recirculation. Under normal circumstances, the engine will have unstable idle speed or flameout.

Waste gas valve, also known as oil separator and pressure control valve, is usually installed between compressor outlet and condenser inlet. The heat transfer effect in condenser and evaporator can be improved by separation.
