i think its quite common to any cars this problem. Guessing its the gasket issue. Have you encountered any overheating ?
White smoke is a bad bad thing my friend. Usually white smoke produced due to pistons eating up your blocks.
Usual solution will be overhauling. (Other sifus, Please correct me if i'm wrong)
It's a valve seal. Do check on other discussion threads. The engine oil is burn in the combustion, thus producing a white smoke. You can check your exhaust tip is still dry. The remedies will be top overhaul. Valve seal can be repair by some workshop but they will need a special tool to remove the valves. It will cost between 3k to 5k inclusive of oil separator change.
