What causes gasoline smell with white exhaust smoke?

A gasoline smell combined with white exhaust smoke typically indicates an issue with the engine, often related to fuel or oil mixing with coolant. This can occur due to a blown head gasket, which allows coolant to enter the combustion chamber, resulting in white smoke. Additionally, fuel system problems, such as a malfunctioning fuel injector, can cause unburned gasoline to exit through the exhaust. It's advisable to have the vehicle inspected by a mechanic to diagnose and address the underlying issue.
