Smoke after a brand new turbo

[ruvim]

So I bought a BMW 2018 540 I 55,000 miles. I drove around 5000 miles fully stock and my turbo blew my warranty covered it. I have a brand new turbo the next day that I drove the car with a brand new turbo my car started misfiring. I checked the code. It said120408 - Charging pressure control: Switch-off as consequential reaction.
140001 - Combustion misfires, several cylinders: Fuel injection is switched off.
140010 - Combustion misfires, several cylinders: detected.
140601 - Combustion misfire, cylinder 6: Fuel injection is switched off.
140610 - Combustion mistire, cylinder 6: detected. so I went and bought a new coil pack for cylinder six and I bought spark plugs for each cylinder. The misfire is stopped for now, but I keep getting slightly blue Smoke I’m not sure if that smoke is from the misfires or from a brand new turbo. The shop did say that it’s gonna smoke for a couple days but I’m still worried there’s a little bit of oil around the PCV and the oil cap. I have zero codes right now. Am I chillin or is it my pcv valve cover? Because I checked my pcv gasket and it’s fine. The smoke goes away after the cold start and there’s no smoke when I drive the car.

Smoke on startup is usually leaky valve seals or oil reside in the intake tract somewhere that’s allowing oil to pool up and get sucked in at startup. Sometimes even a ring issue can cause this, but you’ll tend to have smoke at other times too. The dealer should have cleaned up all the oil that was spewed by the turbo unless it was a pretty big blow and your exhaust got filled with a good bit. If that happened, then only time and lots of WOT to heat up the exhaust and burn it off will be your only fix and that’s IF it didn’t just pour out from the turbo because the center seals went and it was leaking bad. I’d do a compression check at bare minimum to make sure all cylinders are base healthy, especially since you bout it and had issues within 1k miles. If anything is off, take that shit back.
