If its coming out after the engine comes up on its normal operating temperature. I would say coolant is burning in the combustion chamber/cylinders.
Could be blown headgasket, cracked head and block. Best get it block and pressure tested to be in the safe side
The oil drain bolt will not cause the white smoke unless you ran out of oil completely and the engine overheated big time because of no lubrication then we can blame it for the caused.
