What Cause White Coolant Smoke?
What Cause White Coolant Smoke? Following up on another topic - what all causes coolant to come out of the exhaust on a HOT start?
They don't seem to get it so much on a cold start, but when they were at the track, starting it back up when it had only been sitting a minute or two caused a definite coolant smoke to come out.
I know blown head gaskets and bad rings (or ringlands?) can cause this, but is either one more tied to doing it on a hot start?
His car doesn't seem to do it much when driving around or when getting on it, and his power wasn't down much at the track today either.
Any thoughts?

Re: What Cause White Coolant Smoke? Unless the block is damaged..i.e cracked cylinder or a warped block deck...It is the head/head gasket. A warm start up causes this more because the cooling system has 15 psi of pressure in it forcing it through the leak. When the engine is cold, its only the pressure from the water pump causing the coolant to leak by.

Re: What Cause White Coolant Smoke? when my injector was hung open, it would cause the same thing. looked like coolant but noticed no coolant loss or higher engine temp. maybe he has an injector dripping. Mine did not do this at wot tho....just startup. Could be a head gasket/head/block/ if its not running hot tho....
