Sometimes when I start the car, I get some white smoke out of my exhaust for like 3 seconds and it goes away. Is like white / gray / maybe a light blue shade. Any ideas , is this bad.
Hopefully it's just a little harmless condensation burning off. We don't have that here in 116 degree weather . Otherwise it could be the signs of coolant burning (blown headgasket). A symptom can be the exhaust smells sweet and is blueish-white.
