What does it mean when white smoke comes out when i start up my car. it does this until it warms up and goes away. then it lightly comes out more but once i drive the car around once it goes away. and after that i dont see the smoke until the car cools completly down.

Answers from the Automotive Experts

Amanda J. Pierce, MBA Joe, Thank You for writing into AskPatty!! White smoke is often simple water vapor, this is especially noticable on cooler days. If you are still seeing white smoke on warmer days, you may have an issue of leaking valve stem seals, or a failing PVC valve(positive crankcase valve). This can often be a cheaper fix, in narrowing your problem. I would recommend replacing this first, before further diagnosis. White smoke is also indicative of burning antifreeze if you have a leaking head gasket, which hopefully is the least of your worries.

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Joe, White smoke at start up is normal. You're just seeing condensation burning. If it continues after the vehicle is warmed up it's most likely a bad head gasket and the white smoke is burning coolant. Lori Johnson
