Every now and then I get puffs of white smoke coming out of my tail pipes. It does not happen all the time, just now and then after the car has idled for a little while.

Car still runs great, no loss of power, could it be pcv valve or antifreeze getting in system.

tks

White exhaust is usually indicative of antifreeze in the combustion chamber, BUT, that's not 100%. If you have a coolant leak to a cylinder, it will be most noticeable on a cold startup. Have you had any significant coolant loss recently? That usually an indicator. Coolant doesn't evaporate, it has to be going somewhere. Hope this helps, let me know.
