Why does Mondeo always have oil in the throttle?

When the engine is running, it will produce exhaust gas. At the position of the air cleaner, there is a pipe connected to the upper cover of the engine to exhaust the exhaust gas. Driving a car for a long time will always produce exhaust gas. Even if it can be discharged, it will definitely leave a little at a time. Over time, many a mickle makes a mickle, resulting in the situation you mentioned.

The most important part of the engine system of the throttle EFI vehicle, its upper part is the air filter, and the lower part is the engine body, which is the throat of the automobile engine.

So be sure to clean it often. If there is a lot of waste engine oil, it will have a great impact on the operation, driving and idling of the car, and it will also have an impact on fuel consumption. Hope to help you, hope to adopt!
