1 Answers
Methods to determine if the exhaust gas valve is damaged: 1. Unscrew the clamp screw at the throttle port, remove the air pipe, insert the oil dipstick, probe to the bottom and then take it out for inspection. If there is oil on the dipstick, it indicates that the exhaust gas valve is damaged; 2. Start the engine and let it idle, remove the vacuum hose, and connect a manual vacuum pump. After pumping, apply vacuum directly to the diaphragm chamber. If the engine does not experience unstable idling or stalling, it proves that the exhaust gas valve is damaged. The exhaust gas valve, also known as the oil separator or pressure control valve, is installed between the compressor outlet and the condenser inlet to improve heat transfer efficiency in the condenser and evaporator through separation.
