White smoke from engine

Hello,

Usually white smoke is indicative of coolant being introduced into the combustion chamber and being burnt in the combustion process of the engine. It is usually accompanied by a sweet smell and the need to regularly add coolant. This is usually caused by a blown head gasket.
The other problem, having to regularly add oil, could be an oil leak somewhere. I have included a few links for you to go to down below.
