The engine in my truck has developed a noticable tap, quite loud when cold and still audible when warmed up.
Sounds like a valve train noise to me and seems to run ok.
Went to the dealer today and they basically said it's a normal LS engine noise.
I disagree. I had a 2000 that had piston slap, an 04, 07 and 08, none of which were noisey.
They said they would log my concern and if something breaks, they will fix it.
I would rather not break it in the first place.

Any know issues with 6.2 engine noise, it is not displacement on demand equipped.
I checked TSB's today and didn't find anything.
