White Smoke cold start up in Cold Weather (turbo cars)
 

has anyone been getting white smoke during Cold Start?

im on e85 and i always see lot of white smoke but no overheating and no loss of coolant.

anyone

Does the smoke linger or does it disappear quickly. Can you tell if there is a slight blue tint to it. ? Lingering and blue tint smoke is oil. Fast disappearing smoked. (Slower than steam) is coolant. Neither are good. Best case scenario the seals in turbo are slightly leaking. Are you letting car idle for 30-60 seconds before shutting off after hard driving. You can YouTube smoking turbo car could help to identify smoke

Do you park your car outside in a high humidity area? We've seen some turbo cars get a lot of condensation in the exhaust while sitting, causing a puff of smoke on startup.

looks like white smoke, i always let it idle for 5 min after driving hard

i live in LI NY, humid and now its cold at night but warm during he day

Temp differences cause condensation, the same way a glass of ice water forms water condensation around the outside of the glass.

Turbo cars (and all cars actually) have super duper hot exhaust systems while running, and if it is humid outside, a lot of condensation will build up inside of the exhaust system after shutdown.

When you first fire up the car, the water in the exhaust system gets hot and turns to steam. You can see this on many cars on cold mornings at stoplights.

Turbo cars have the turbo which gets even hotter, and cools slower, causing even more condensation to accumulate.

Try stuffing a rag in your exhaust tips next time you shut the car off after driving for a while at full temp. This I think would stop any condensation to accumulate, and you shouldn't see any steam, and if you still do, it then very well may be smoke.

Smoke will linger, and not disappear, whereas steam will quickly go away.

great explanation

my smoke doesn't dissapear for like 10 min after that no more smoke but on cold starts on cold mornings but when weather is hot.. smoke for like 3 min and disappears

E85 makes it worse.

i can see that...

btw, u like my new signature?

:bellyroll::bellyroll::bellyroll:

Gotta take me out in this thing some time :party0030::happy0180:

Not thread jacking but do you guys tend to see water a lot ?

when i was straight piped it would blow water out, but with the stock exhaust back on nothing

With E85, water blew out of the exhaust during Dyno tuning. With 93 not at all.

I am not sure what this Cold Start you speak of is. :lol: As long as it isn't smoking once the car is nice and warm, I wouldn't worry about it.

Hate u lol

When its warm it only smokes for 2 minutes
