Check the oil level n the crankcase and make sure it is not overfull.
And check to see if your oil has a faint smell of gasoline.
thanks Dave
1: it is still the original
2: the oil level is below the maximum level
3: no gasoline smell like when it gets flooded, classic exhaust smell
white smoke does so only when the engine is cold and in any ambient temperature
when the engine is hot, the problem does not arise
