My Kia Rondo 2008, after a long drive, the next start will have white smoke coming out of the exhaust pipe. Smoke coming from the exhaust is an indication you have a blown head gasket, a faulty cylinder, or a cracked engine block that is causing the coolant to burn. Reasons For White Smoke From Exhaust Thin White Smoke: Condensation Buildup. Dirty Cabin Air Filter. It is caused by the condensation of water vapor in the exhaust system due to the temperature differential between the exhaust gasses and the cold environment. The smoke only occured after the car sat overnight - never at the end of a workday. Was no charge. Bad glow plugs. When you start a cold engine, the computer commands a rich fuel mixture. If you have mis-fuelled your car, it can often result in white smoke from the exhaust on startup then goes away. It doesn't do it while driving. I can then restart the car w/o seeing any smoke. ue cw hg iu tx lp wd vn va rc
