This can occur if coolant is leaking into the head. It could also be as simple as water entering the exhaust or carburetor after the engine was pressure-washed. On the other hand, if the smoke is a bluish white, oil could be bypassing the rings on the piston or valve seals and being burnt in the combustion chamber.
