This is fine, the smoke is caused by oil flowing pass the piston rings when the engine is shutdown. its not an issue

This is probably just condensation in the exhaust, if you are not loosing coolant that would be me guess.

Ouch! you've got engine coolant in the exhaust from a leak somewhere...DO NOT run this engine until you get someone (dealer is best in this instance) to diagnose ($50-125)

SOURCE: Suzuki Vitara V6, MAF sensor, white smoke.

i have a simialer problem but i was getting neat fuel out the exhaust as well . i removed the engine because id got a replacement then stripped the old one and as i thought it was a valve timing problem.looking at the engine from the front the cams on the left bank had jumped one tooth out of time so fuel was not being burnt and coming straight through the exhaust.strangely it didnt seem to have a big missfire and idling and smoke got worse when warm.

How come my truck blows out white smoke for the first minute after starting it and then is fine after that???


the white "smoke" is probably water vapor from combustion in cold cylinders
as the engine warms up it is super heated in the hot exhaust system and is no longer visible to the eye

I have a Ford Focus 2.0 litre zetec engine on a x plate. When I start it up from cold it bellows out white smoke for about 2 mins then clears and is fine until the next day. It is not losing water and is...


White smoke on start up of a cold engine is water vapour created by cold moist air and hot combustion ( steam). Mostly all cars will emit a whit wispy smoke until temperatures are elevated enough for the cat converter to turn it in something you cannot see. To be sure have a compression test done to check for gasket and have a coolant system pressure test done to check for coolant leaks

What does white smoke mean?


With a petrol engine, water/coolant is being burnt due to blown head gasket.

White smoke from BMW 740i exhaust


white were? the exhaust tip, or other spot, long pipe, name spot?
white, is steam or OIL.
oil smells like burnt oil and takes for ever to dispate
steam is water, and smells , sweet due to 50% glycol inside.
and goes away fast.
but all Gas engines make water at all the time running as a by product of combustion and for sure on cold days, some times full time cold
due to climate effects.
does your neighbors car smoke at same time, (look)
bingo , dew point.

all gas engine smoke cold started, (steam)

so first find out what it is,
take the dip stick out of a hot engine. stalled, drip it on the exhaust
see that smoke ,smell it? that is burning oil
now you know what you have, steam or oil. smoke.

I changed the turbo now white smoke coming out of my exhaust


This seems to be a symptom of a blown head gasket.
White exhaust smoke is an indication of water / coolant in the exhaust. The car running sluggish and using lots of fuel can be caused by compression loss.

Look at the coolant level color and smell (with cold engine - don't open the high pressure reservoir with engine hot as hot coolant may spray you in the face). If you have a blown gasket, the coolant color may become brownish and it may smell bad or the level will get lower even if you have just refilled the cooling system.

What you can also check for is bubbles in the reservoir. With engine cold, remove the reservoir cap. Start the engine. Try to rev the engine (or have someone do it) and observe if there are bubbles in the reservoir tank. If you see lots of bubbles, you have a blown gasket.

My harley smokes


all engines do cold. its water vapor and or the hot exhaust, causing the air, to change dew point, (looks like steam)
on the white smoke smells like burned oil , it is, and is slow to dissipate like steam, (see moms tea pot , and steam fast dissipation?)

if it is oil , its most likely bad valve guides and seals, or both.
if a compression leak down test passes, its not rings, (mostly)
