This is a common & expensive CAT 3116/3126 engine failure point, which is easily prevented by proper fastening of the air compressor bracket.
Fix/PM: before selling (ie GP) or driving your LMTV / FMTV roll under the truck's oil pan, driver's side, and look at the air compressor bracket-- confirm all the bolts are in & tight.
