It sounds like you have a bad head gasket. Coolant is most likely getting into the combustion chamber causing the smell. Also, coolant creates white smoke when it burns. If you see that, it reinforces the head gasket. Make sure no coolant is mixing with the oil. You don't want to damage bearings and other internal engine components.
