Check your coolant level. Could be a blown head gasket or worse, a cracked block.

"What" could it be? Oil smoke is a blue ish and coolant smoke is white check the radiator for oil and the oil for coolant

00_LS1_T/A

Oil seems fine and no oil in radiator

KevinR

Is it constant smoke coming out, or only when you go WOT? Are you sure it's white? Can you post a video of it smoking?

If it's white smoke all the time, especially on a warm day with the engine fully warmed up, then it's most likely coolant being burned off from some sort of headgasket problem.

If it's only at WOT and only when cold outside with the engine cold, then it's normal and nothing to worry about.

white smoke headgaskets? do a leakdown and check but white smoke can mean headgaskets

^^^^^^^ What he said. Pressure test you radiator and see how well it hold pressure. Listen for leaks when you pump it up.
