Started seeing some light blue/gray smoke on cold start. Mostly after sitting overnight. 36K miles 2020. Took a video this morning and went to dealer. Showed the service writer (who I've dealt with a few times, good guy) so they can't say they can't duplicate it. Can't see me for 2 weeks. Like getting a Dr appointment. Truck doesn't consume any noticeable oil between changes. Only happens for about 3 seconds.

Normal. Then why haven't I ever seen it before and what's the cause. It's not condensation vapor, that's white. You guys sound like a Harley dealership. Everything is normal.

Blue/Gray...Bluish Gray as in oil burning. How would you describe it?

A bad joke misfired. Sorry.
No problem. You should see the sarcasm on the Harley website, but the first 2 guys telling me it's normal is BS. There's an oil leak somewhere. If it was fuel it would be black. I've been around high performance cars for longer than a lot of you have been on the planet, except this is my first turbo.
Usually this would be valve leak down.

You stand at the back of your exhaust every time you start your truck? :think:

From your video that is not something I would ever notice. It’s more than likely just carbon/soot in the exhaust that has accumulated and gets blown out of the tailpipe with the condensation from a cold start.
