Throttle motor leaks oil.

Pull off the intake pipe. If you find oil stains on the accelerator, you can even drop a drop of oil. This is also normal. Because the side wall of the intake hose is connected with an engine exhaust gas circulating pipe, the engine will continuously suck the oil and gas generated by itself into the cylinder through the throttle valve for combustion. The throttle oil leakage you see now is actually the reason why the oil vapor is not completely inhaled.

It doesn't matter for the time being. It's normal.

In addition, remember to clean the throttle and intake manifold regularly, which will help the engine to burn fully and keep the power young for a long time! _ I hope I can help you.
