Just this weekend after driving the car 150 miles, I pull into the parking spot, and I see a cloud of white smoke coming from my driver's side fenderwell. So I popped the hood and got a quick whiff of coolant and then it was gone. The car is not overheating, and the fluid level is not noticably going down at all. The cloud of coolant only seems to be present after hard and/or long running. I'm not burning any coolant (that I can tell), so where should I be looking first. Intake, hoses, etc....????
