Head Gasket

So me and my buddy were going sears to exchange some tools (because somebody likes to use the smallest drive possible) and we were driving up on 885 right by the old outback steakhouse. I pulled up to the light and i noticed a bad vibration and very low rpms. So i looked in my mirror and i saw a huge wall of white smoke. I pulled over and saw coolant just shooting out of my exhaust. So i parked it and called for a ride. But my question is i didnt think head gaskets broke like that. I always thought they showed signs like using coolant or coolant in the oil. IDK… but it looks like a good time to do a cam and rr’s!

first what kind of car is it?
depends on what goes. have seen blown head gaskets leak slowly or blow out all the sudden.

well if coolant is shooting out ur exhaust, it sounds like the head gaskets let loose

Damn…Thanks
