[CoreyAnn]

You can determine whether the exhaust valve is damaged by checking if there is blue smoke coming from the exhaust pipe. The specific explanation is as follows: After the exhaust valve is damaged, it will cause the car to burn engine oil, resulting in severe blue smoke in the exhaust. Because the exhaust valve is damaged, the engine oil burns faster, and consumption increases. Open the engine oil filler cap—if the suction is severe (i.e., the cap is pulled in), it indicates a problem with the exhaust valve. Relevant information is introduced as follows: The exhaust valve is commonly referred to by its colloquial name; the professional term is the pressure control valve or oil separator. The exhaust valve is installed between the compressor outlet and the condenser inlet, improving heat transfer efficiency in the condenser and evaporator through separation.
