Normal
My 2018 went in for cam phasers today. The noise at cold start began about 2 weeks ago. Last friday, it was knocking at any speed unless it was under load. I was about 150 miles from home when it got really bad. Wasn't sure if I was going to make it back or not. My mechanic didn't seem too worried. But we'll see in a day or so when he opens her up. Ran fine.... but sounded real unhappy.***EDIT - I should add that records showed they were last replaced in 2020, before I bought the truck.
