Smokey on Start UP ?

[zeroptzero]

When I start the car after sitting for a bit overnight, I see smoke out the back in my mirrors. I can't discern if it is smoky like oil or carbon, or if it is water vapour ? Does anyone else see this on their cars, it is hard to tell as I am in the car and not seeing it form the rear. Anyone else see this on their cars. I am still going through break-in at 1,400 kms, I will be swapping out the oil this week.

Have any build-up on your exhaust tips?

Is it cool out in the morning? Probably moisture

Yes - once on a cool morning - it was steam…. But it did make me look. lol

Does not happen on warm mornings.

Its water vapour.

Or your cylinder head is cracked and your burning coolant in the cylinders

Nothing unusual , a bit of carbon

It isn't overly cool, but cooler , it seems to come out in a big puff and then goes away

I need to see if there is some colour to the smoke, maybe get my son to start it up next time and I wait outside

I need to have someone start the car while I am outside of it. I understand water vapour if it happens during cool temps, but some days it is warm afternoon start up. The key thing is that it happens after sitting a while , like overnight. I don't know if it is fuel being dumped in during cold idle , I had a Subaru WRX that did something similar, like the catalysts weren't able to operate quickly on cold start with added fuel being dumped

Alright. Maybe take a video and keep us updated

Don't bother anyone.
You're a strong independent Canadian, so Do It Yourself!
1. Tape a shop vac hose to one of the tips.
2. Tape the other end to your face.
3. Crank.
4. Sniff.
