It does it at every start up. First thing in the morning at 7:30 am then when I leave for lunch at 1:00 pm and then at the end of the work day at 5:00 pm.

Had oil checked said it looked good and clean. No fluids leaking under the car. Do have black stuff and water in the tailpipe.

Good afternoon,

White smoke is an indication of burning coolant.

You either have a leak of coolant going into the intake manifold or a head gasket leaking.

I would have a leak down test done to eliminate a head gasket. That is when the remove the plugs and put shop air into each cylinder one at a time and see if there is any coolant movement in the radiator.
