ethylene glycol, it is coolant being burned which is not good.
The sweet smell is the anti-freeze in your coolant. The white smoke is from the water. Water is getting into your combustion chamber (cylinders). This could be from a blown head gasket, a warped or cracked head, a cracked block or a blown intake gasket.
Fill your radiator and run the engine with the radiator cap off. If coolant is forcefully flowing from the radiator, then you most likely have a blown head gasket. This is much easier and more telling check than doing a compression test on each cylinder.
If the car is not overheating when you drive, check your oil for water (it will look milky). That would most likely be a blown intake gasket.
that question has been asked many times, and it is because there is sugar in the gas tank. If you continue to drive it that way, you will ruin your engine soon..You will need to have the entire fuel ststem flushed clean and your fuel injectors replaced.
your burning the coolant/anti freeze through your exhaust. Most likely a bad head gasket or a crack in the cylinder head.
