Smoking on startup after sitting

I have a 2020 Explorer ST. On startup, smoke appears out of the exhaust, sometimes it is light, other times it is heavy smoke. I took to 2 different dealers and they said they could not replicate it and thus could not address. Has anyone else experienced this? I have attached 3 different videos showing what I'm talking about.
I too have a 2020 explorer platinum with only 9000 miles and it too smokes when I first start it after sitting and I can tell you that it's definitely oil smoke and I don't know anymore at this point until I investigate further!

Can anyone contributing here, saying that they have startup smoke, update us on your environmentals?
- Park indoors or outdoors?
- Is there an overnight temperature variable? (Under 50*F overnightnight, smoke, but above 50*F overnight, no smoke)
- Park at an incline (grill up), or at a decline (grill downwards)?
- Park at an angle (driver's side higher than passenger, or vice versa)?
- ^ Following up - which exhaust pipe smokes, pass, driver, or both?
- What oil do you run?
- Have you found oil in your hot-side tubes? If so, how far up? (turbo outlet, hard plastic pipe, intercooler inlet, intercooler outlet)

What type of oil are you using? I found that synthetic blend leads to a smoother cold start up, at least with my ST.

Hey guys, thought I’d join the “club” here. Had the same issue. Showed a CEL. Have about 30k for reference.

Took to dealer. Had a faulty purge valve. Had it replaced. Hoping that was the source of the issue.

oil catch can was recommended. They can install at the dealer.

Hello! My 21 st is in shop for this problem parked incline smoke out of exhaust immediately after start. But mine was using antifreeze. Currently motor is out and being dissembled because they found scoring on number 2 cylinder. Give update when i get it back. Probably trading it in. 50,000 miles

Mine goes to the dealer tonight for this. I have video of it. The blue smoke is most noticeable if the car sits for two days or more.

Well that’s when I first noticed it, I started up and saw the smoke roll by my window! I thought it’s not cold out why am I smoking?

Thanks, was just wondering if I needed to stand behind it and remote start in order to check for smoke.

The dealership has mine now for this. Found the passenger side turbo leaking oil. They're trying to verify the driver side turbo, too, but they say it's harder to get at. The car has to be on a slight incline (nose up) and not run for a couple of days. 2022 with 17,000 miles.

A slight incline? That’s interesting? And yea mine sat for a few days till I started and saw the smoke blow by while I was sitting inside it, well at least your mechanics are really looking! Hopefully mine will do the same

Another update. ST still smokes after sitting.

I keep buying Explorers because I really like them but this is getting nuts.

I had same issue. It turned out to be oil leaking into both turbos.
Ford had to replace both of them which solved the problem.

Yea so got a call, nothing is leaking, oil smell from spill on cover, could not replicate smoking, recommended oil change due to close to have oil change, did they check turbos? No was no need to? So oils I smelled from exhaust is coming from the mess they made? Oil change will come next week but they want oil change cause they want money cause this was a warranty job so they ain’t getting paid. Other than the normal hourly wages, this is why these forums are made people have issues and read about them but god forbid a mechanic looking and reading and going ya know might be something to this?

So I now see on my ford app they have changed my oil without my permission? And they say they can’t replicate the smoking? It’s ok I have the video in their parking lot
