Recently, oil was found in the air filter box, that is, at the entrance of the throttle valve. What happened? Is there the same case? The oil is normal. It is the crankcase ventilation pipe that sends the oil vapor back to the air inlet and then burns it. However, it seems that the air cabin of the landlord is not tightly covered or something. It stands to reason that there should be no dust in this part You are not normal. How to filter the air conditioning filter element, and how can there be oil in these positions? See where the oil leaks and take the time to do maintenance. 1. Check whether the air filter is blocked or wet. If the air filter is blocked, the intake resistance of the engine will be too large, and there will be oil backflow at the intake of the engine. Also, your car has no supercharger. If yes, you need to check the working condition of the supercharger. If the seal of supercharger fails, there will be oil leakage, and the air filter will also have oil. 3. Poor sealing of the valve oil seal will also cause oil leakage at the air inlet, and there will be oil in the air filter, which needs to be measured by checking the oil consumption. If the amount of oil (mileage or oil change interval) added during the oil change cycle is too large, it is necessary to check the valve. You need to check the amount of oil in your oil pan. If you add too much oil, the pressure in the crankcase will be too high, and there will be oil in the air intake and even the air filter. Just put away the excess oil and add it to the standard range. @20 19
