Several months ago my M816 developed a knock, a loud one. No drop in power, oil pressure or any of the standard indications. A light blue haze from the exhaust that wouldn't go away was all that was evident. Well, after narrowing down where the knock was, #3 piston, I disassembeled it. I'm adding a lot of pictures so you can see what's in side these monsters.
I took the pistons to Cummins and they diagnosed the problem to be too much use of Ether. Then I took it to a Cummins Mechanical director and he said "if the engine had been purchase by me from Cummins it would be a warrenty item and they would repair it. He called it "cylinder liner distortion" and it should have been caught at time of assembly. Oh well, 2 new liners, 2 pistons,rings and bearings and a bunch of gaskets and the big guy is purring.
I hope these pictures help someone understand what's under the hood
