Cam phasers are across every 3.5 Ecoboost. Expedition, Navigator, F150, Raptor...
They are covered under warranty, but supposedly also it doesn’t hurt anything. There are plenty of videos out there that detail the issue. I also posted a link around here somewhere.
My guess is Ford is aware of issues long term with the phasers. I've seen lots of people talk about extended oil flow issues and other things. If Ford can publish a TSB saying rattling turbos are normal and won't cause an issue, then I would think the would do the same for the VCT noises if there wasn't a chance of something more serious going wrong, the cost of potentially repairing every single engine would bankrupt a company...
