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.

Its water vapour.

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

Don't bother anyone.
