white smoke coming from exhaust Sign up here! Search this forum this category all forums for All words Any words Whole Phrase (search options) Auto Repair Home>> Automotive Repair>> Car Troubleshooting Guest Anonymous Poster Aug 23, 2006, 8:29 AM Post #1 of 4 (2305 views) white smoke coming from exhaust Sign In hi there...i recently had my car repaired and now i have a new problem. white smoke is coming from my exhaust pipe. my first thoughts were that somehow coolant was burning. i checked my radiator and it was completely full and my coolant resevoir seems to be normal as well. my oil levels are good and my engine doesnt overheat. i talked to a few mechanics and one said it could be steam meaning i have a water leak. he said that its possible water was leaking into my oil pan making my oil levels appear to be higher than they really are. another mechanic guessed it was either coolant or gas burning. i pray its not gas because that sounds dangerous. it didnt smell like burning gas to me. now a third mechanic is guessing that im burning oil. he said to just keep checking my oil and water levels. he said i should be fine just keeping the levels good but to cure the problem i would need to overhaul my engine. ive also been told i might have a cracked or blown gasket head. you could imagine this is leaving me pretty confused. i know close to nothing when it comes to engines so i dont even know where to begin. if anyone could offer some clarity or maybe a gameplan i would be extremely appreciative. Thanks very much.

Black = fuel burning excessivly Blue = oil burning Some cars can burn auto trans fluid thru a diaphragm used for shifting and it will look very light and will have a burn oil smell. You can test as I think is probably a head gasket or head problem by pulling the spark plugs and they should look about he same. A real clean one is burning coolant usually and some further tests. It doesn't take much coolant to make smoke and you should carefully monitor the levels of all fluids. If that is found the head should should be checked out carefully. You've had a lot of shops look at this and if they are in the biz should know what to do??

I had this happen once to me on a Nissan pickup. The smoke was so thick that you could hardly see the truck. steve01832 Veteran Nov 4, 2006, 11:53 AM Post #4 of 4 (2197 views) Re: white smoke coming from exhaust Sign In If the smoke is white, and it looks like you're doing mosquito control spraying as you drive down the road, you likely have a bad head or intake gasket. A shop with a 4 or 5 gas analyzer can confirm by checking tailpipe emissions at the radiator cap. If you find a shop that has a smoke machine, they can check for it too.
