i was driving yesterday night and it was sprinkling and i have a cold air intake so i was causious about puddles and such. i drove for about 20 mins and stopped at someones house. then about 15 mins later i drove probably 2 miles and started to see white smoke coming out of my exhaust, i stopped and turned off my car and let it sit for about 20 mins and check my coolant and everything was okay, it was still full. then i turned on my car to see if there was still smoke and i rev'ed it to 3000 rpm and little bit of smoke came out, i then rev'ed to 6000 rpm and a big cloud of white smoke came out(looks like seafoam) then i just turned off my car. My car isnt overheating, it isnt throwing and codes nothing.!!! can anyone help out this is my daily... thanks

 

how white? could just be water in exhuast. my friends civic does this all the time, but everythin with his is just fine.

 

what is/was the temp?

 

the color is the white looked kinda like when you start up your car in the morning but a little darker and the temp was probable a little above cold its like the normal temp like 1/4 of the temp thing.

 

what was the temp outside?
you may just be seeing condensation,

 

the temp was about 60? not to sure it was around 10 at night. i dont think its the condensation because i drove it for about 20 mins and i think the car would be warmed up already? as i leave the car on longer and rev it more white smoke comes out of the exhaust.

 

hmm, your car should be fully warmed up after 20 minutes. even after driving for awhile if my friend revs it will smoke, when he pulled his muffle off, he held it up side down and it was full of water.

 

you probably burnin coolant

 

hmm okay ill probably take apart my exhaust to see, but when i was parked i parked under a roof so there wasnt any water that can hit my car..

 

ive checked my coolant and its still full..

 

bump

 

white smoke is either coolant or water you got any leaks or anything that u kno of?

 

bump!! i checks and theres no leaks, you guys think it might have to do with a map sensor??

 

help anyone??? :/

 

try revving ur engine again on a clear dry day and see if it happens agains if it dont then that mean u probably sucked up some water and if do happen again then its burning coolant, just because the level is good doesnt mean there is a small leak

 

White Smoke
1. Burning Coolant
2. Water getting into the Head gasket
?
might have blown head gasket? Do you have a CEL?

 

have u changed ur pistons or anything like that?Cuzz im having a simlar problem but i have 12 and a half high compression pistons and i was told because they didnt meassure the gap with the pistons theres probably little bit of oil going threw gap but my car runs nice except when my vtec comes on burns alot more oil then normal but if im jus sitting i notice white smoke as well more then normal some times but when i drive and stop its not bad at all but i dont know if its cuzz of the cold

 

bump!!! can a bad iacv cause the white smoke?? or a bad map sensor??

 

smells like burning coolant but i dont see the coolant level goiing down, and i checked the head gasket wasnt blown, no cels

 

um i havent changed my pistons yet barely have like 60,xxx miles on the enigine. this just happened all of a sudden.. when i drove it for about 10 minutes white smoke started to come out but not a whole lot.

 

How did you check the head gasket?
A blown head gasket will not allways throw a code untill it messes something else up.
Get someone to use a block tester on the car it will detect combustion gasses in the cooling system.
