Why does the throttle valve supply oil?

1. If there is a small amount of oil on the throttle, it may be that the oil flows to the throttle through the intake belt. This phenomenon is normal, and car owners don't have to worry too much.

2. If there is too much oil in the throttle, it may be that there is a problem with the seal of the turbocharger, which causes the oil to enter the throttle. It is necessary to check whether there is a problem with the seal of the turbocharger.

3. It is also possible that the engine crankcase exhaust gas circulation system has failed. If the exhaust gas circulation check valve is damaged, the oil will enter the throttle valve and need to be replaced in time.

Treatment of throttle oil intake:

1. Replace the oil-gas separator.

2. Replace high-quality engine oil and seals. Million car purchase subsidy
