Product Description
When the pressure control valve of automobile valve cover fails, the following problems may be caused:
1. Oil leakage: The failure of the valve cover pressure control valve may cause the oil-gas mixture inside the valve cover to leak. This will lead to oil leakage to other parts of the engine, which may cause oil pollution and corrosion, and even cause the risk of fire.
2. Engine fire: The failure of the valve cover pressure control valve may cause the pressure inside the valve cover to be out of control. This may cause the oil-gas mixture inside the valve cover to enter the cylinder, causing poor combustion, leading to engine fire or unstable operation.
3. Engine performance degradation: The failure of the valve cover pressure control valve may cause the pressure inside the valve cover to be too high or too low. This will affect the normal operation of the engine, leading to the decline of engine performance, including power weakening, poor acceleration, fuel economy decline and other issues.
For the inspection and maintenance of the pressure control valve of the automobile valve cover, the following steps can be taken:
1. Visual inspection: First, visually inspect the appearance of the valve cover pressure control valve for obvious damage or looseness. Check the valve body and connecting parts for signs of oil leakage.
2. Pressure test: Use a professional pressure test instrument to test the pressure inside the valve cover. By measuring the value of pressure, it can be preliminarily judged whether the valve cover pressure control valve works normally.
3. Check the sealing performance: check the sealing performance of the valve cover pressure control valve. Ensure that the valve body and connecting parts are well sealed to prevent oil and gas leakage.
4. Replacement or repair: If it is confirmed through inspection that the valve cover pressure control valve is faulty, it needs to be replaced with a new valve or repaired. Select the valve cover pressure control valve suitable for vehicle model and engine, and ensure correct installation.
It should be noted that if you don't have relevant technical knowledge and experience, it is recommended to hand over the inspection and maintenance work to a professional automobile maintenance technician or service center. They can accurately diagnose problems and carry out maintenance through professional equipment and experience to ensure the normal operation of the car. In addition, regular maintenance and inspection of vehicles and timely discovery and repair of valve cover pressure control valve problems can avoid more serious damage and safety hazards.
