A blown head gasket would make the coolant leak into the cylinder to be burned off during driving. Smoking from the tailpipe under hard acceleration is a good indication. Checking your oil would be a good way to check. If it looks really thin or dis-colored
I would also check near the heater core inside the car. Coolant lines run inside the car then back out for heat. You may be leaking inside the car. Probably behind the dash
