I purchased a 2500hd in October. Since buying it has been back to dealer for a knocking noise when accelerating in first two gears between 15000-2500 rpm. The first episode the trick through a code for the knock sensor but dealer replaced rocker arm for cylinder 1 which failed. Since then all rocker arms have been repaired but engine knock still there and very obvious on cold start but fades after thirty miles or so. I owned a 95 Silverado and a 2004 Tahoe and I’m familiar with the Chevy acronym (can hear every valve yelling) lol. Anyone have suggestions on what to tell dealer so the problem can be resolved.

Yeah, do a site search on GM AFM.
Cylinder #1 is one of the AFM cylinders.
Was it a used truck, or a demo?
