This issue affects all 2011-2013 5.0L Coyote engines and some of the early build 2014 models as well.
This video shows what the sunken valve problem looks like.

I wonder if it’s truck Coyote only or if the Mustang coyote is having similar issues?  I know 2nd gen truck Coyotes are having cam phasers go bad all the time.  Haven’t heard of any mustangs doing this.
