This car smells of engine oil. What should I do?

We must first determine where the smell of gasoline comes from, whether it is the engine compartment, the exhaust pipe or the car.

In the exhaust pipe, it may just be caused by insufficient combustion of the cold car.

If it is in the car, there may be oil leakage somewhere in the oil pump assembly.

If it is in the engine compartment, it may trigger the following conditions simultaneously:

First of all, the only way for gasoline to reach the engine fuel tank is the combustion chamber in the engine, that is, the cylinder.

Secondly, there is a condition that the gasoline sprayed from the nozzle will not burn when the engine is working.

Third, the cylinder is not sealed, so there is gasoline in the engine fuel tank, which means that the spark plug of one cylinder is not lit and the piston ring of this cylinder is not sealed.
