Live with it? You have warranty. You will lose power if the waste gate not sealing/working. I would would trade it in.I have a slight rattle coming from the driver side turbo on cold starts. I’m thinking it is the waste-gate flapper valve in the exhaust pipe flapping like the guy says in the video in the link. Think I should live with it or use the warranty?
I’ll post a video of my Expedition doing it and add the link here.
