Cold startup - white smoke
 
I know this topic has been beaten to death on the forum but I thought I would ask anyways as it does not seem to be very obvious to me. I suspect I am starting to have small coolant leak so I posted a video as describing it can be tricky as it could be interpreted differently by each reader. I hope it is just condensation but I have never seen this before on any of my FC's in the past. This is my first FD so I might be a little paranoid.

I have a low mileage 93 with almost perfect compression. Original engine. I have had to add some coolant after a couple of months after driving so more than 200 miles or so.

After the car sits overnight I don't see any smoke whatsoever on startup. Same after 2 nights. The video below shows the cold startup after 6 days. I don't smell anything sweet in the exhaust but my sense of smell is not great. It only lasts a minute or two.

I'm only worried that when I store it for winter having water in the engine for up to 6 months would not be that good ...

Here is the link. Thanks for your help.

White Smoke?
 
That appears to be steam after warming temps rise.

Looks normal to me

My 7 does the same thing. It's condensation. Waft it. It'll be steamy :) if it was a coolant seal, it would not have started that easy and it would be thick and billowing white smoke. Not transparent and short lived like that :)

Condensation, mine does that when it starts to get cold out, never happen in the summer tho.

looks like condensation, as said if it was coolant it would smoke immediately and likely have starting issues.
