I have an LBZ that when looking up under the pistons with the oil pan off i can see rust colored rings about the size of a quarter above the wrist pins on the piston bottoms. Is this an indication of abuse that can lead to all the pistons failing?

Thats what I would guess as well. Once conventional oil gets much beyond 325-350 degrees, it can flash burn and turn to a grey chalk like substance and cling. Sounds like what you've got.
Well thank you fellers.
Next hurdle is a piston looks damaged from under and has left some scuffing of what might be just piston I cant fully tell as it looks silvery and not deep into the bore.
I have to decide if I want to try and pull the head off see if I can hone it or do I want to sleeve it or return it for my money back.
Whats the going rate for 1 sleeve installed and honed?

Depending on the brand of sleeve, most blocks can be repaired/upgraded with a dry sleeve and be stronger than stock. Dart sleeves are pretty common, but each shop probably has their favorite.
Ya know I didnt ask what it was but I do know the shop I used knew what to do and works on duramaxes a lot. It ended up costing 250. I heard there were 2 types so IDK
Yeah mine was either 200 or 300 per sleeve I can't remember. I called about darton, but I went with another company. Cant remember what it was called
