Rattle sound on startup

[Bronco Damen]

Should I take it in or waste of time?

I have the same sound with my 2.7. I only hear it if I start it in the garage.

Sounds normal. Probably waste gate. I had a rattle in my previous 2022 Bronco 2.7 which sounded like a marble banging around. I replaced a bad PCV valve. The newer version PCV valve addressed the previous design flaws of the old ones. You can tell it’s bad if you open the hood and listen when the engine is on. Sounds like a marble rattling around. It’s a very easy five minute job in the driveway. There’s tons of YouTube videos out there on replacement.
