The white smoke is water left in the muffler, it is drawn in when engine is shut off. It smell like gasoline, because the engine is burning one third of the gas, and discharging the rest with exhaust. http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info
Head gasket
Sounds like you have a coolant leak.
If white smoke smells like anti-freeze, it is more than likely a head gasket.
Maybe a blown head gasket
Telltale sign is WHITE smoke coming from the exhaust that smells like Antifreeze.
probably an exhaust leak, at or near the exhaust manifold
sounds like a blown gasket, allowing coolant to enter the cylinders.
your truck is likely leaking coolant due to a blown head gasket making white smoke and coolant smell
it smells like smoke and u wanna cough.......nah love it smells like rotten eggs!bin there done that.
There is a crack in your crankcase. It will be hard to find due to many problems that can cause it. 1, oil pump is clogged. That is the most common. But if it is already spitting out white smoke it might be to late. I hope I got this to you in time. Good luck. Auston
don't ever smell your car's exhaust.
sounds like you have head gasket problem if the exhaust smoke is white in colour then its engine coolant if its blue smoke then its burning oil you will need to get the engine pressure tested at a garage.
