Just recently replaced a water pump, bout a week later got up to take my kids 2 school went to crank it and there was a big cloud of white smoke not the kind when its cold. I check my oil and water. Im not losing any water and the oil is its correct color. And it has not done it again, but that cant be good! If it is heads would the smoke happen all the time? I dont hav any check lights on and has not over heated now or before. Please help?

Could it have been a puff of oil smoke? I know higher mileage engines sometimes puff a bit of smoke when started cold. I had a Blazer do that for years, actually still doing it every now and then when it's first started. If you aren't losing any coolant and your oil is the correct color I don't see how it could be the head gasket. Hope this helps.
