Sounds like a blown headgasket. When coolant leaks in it causes white smoke. Unless when they put sea foam in your car as part of the tune up. Sea foam cleans carbon and blows out white smoke. But wouldnt explain the missing, and would inly last a few minutes.

When I put sea foam in my car and drove to dairy queen, some guy looked at me and said "dude wtf is wrong with your car?"

check coolant level, if low, may have a blown head gasket, also check oil make sure it's not a milky mess then pull plugs and look for one blown clean due to coolant in the cyl
