Is it normal to have engine oil in the accelerator of a car?

It's normal to have oil on the engine throttle, as long as it's not too much.

Throttle oil mainly comes from engine exhaust gas. During the operation of the engine, some combustible mixture will escape into the crankcase from the cylinder gap. If these exhaust gases are not discharged into the engine, the pressure will increase. Therefore, all engines have exhaust valves to discharge exhaust gas.

Because the exhaust gas contains some gasoline, the exhaust pipe is connected with the intake pipe of the engine in order to utilize the waste and reduce pollution. During the exhaust process, the exhaust gas will take away part of the engine oil, which will remain in the intake system of the engine. Many cars have this problem, which is normal, so don't worry. As long as there is not much oil in the throttle position and the engine does not burn oil, there is no need for maintenance.

There is engine oil in the throttle, which is divided into intake manifold inside the throttle body and intake source outside the throttle body. Generally speaking, it is inevitable to allow a small amount of oil to exist. If your car burns oil or the amount of oil is unusually low, you should pay attention. If your car burns engine oil, the specific reasons should be analyzed and dealt with in many ways.

Reasons for regular cleaning of valves

1, which can effectively clean and dredge the glue and carbon deposit of the fuel nozzle and keep the fuel system clean.

2. It can clean the waste gas circulation system, reduce waste gas emission and save fuel, thus effectively protecting the oxygen sensor and the three-way catalytic conversion device.

3. It can help prevent symptoms such as knocking, unstable idle speed and poor acceleration caused by colloid and carbon deposition.

4. It can eliminate the carbon deposit on the valve seat, lubricate the valve and valve guide, improve the sealing performance, restore the cylinder pressure and increase the power.

5. It can blow off the carbon deposit in the combustion chamber, lubricate the upper area of the cylinder, reduce the wear of the piston ring and prolong the service life.
