What is your question?
White smoke coming out of tail pipe. Does that mean I have a blown headgasket? Last year had a leak in radiator, put in something to stop the leak.

Sounds like a possible head gasket. Have a local shop do a block check to see if you have exhaust gasses in the coolant to confirm.
Yes I have to add coolant when the heat or ac is used.
