BYD l3egr valve slightly leaks.

The following are the symptoms after BYD f3 waste valve is damaged:

1, after the waste gas valve is damaged, it is impossible to control the waste gas circulation, and too much waste gas will participate in the recycling, which will affect the ignition and performance of the mixture, thus affecting the dynamic performance of the engine, especially when the engine is idling, low speed, light load and cold engine, the recycled waste gas will obviously affect the engine performance.

2. The damaged waste gas valve will cause the car to burn engine oil, and the tail gas is blue smoke. The reason is that the waste gas valve is also equivalent to an oil-gas separator, which only absorbs waste gas and does not absorb oil during normal operation. The waste gas valve is damaged, which loses the function of oil-gas separation. At the same time, the engine oil is inhaled, which makes the engine oil enter the air inlet and combustion chamber, causing the engine oil to burn and the tail gas to emit blue smoke.

Replace EGR valve, spark plug, oil and the inside of dipstick. Replace and clean the engine compartment of the throttle cover (the cleaning liquid is included).
