Riddle me this.

Isx 475 cm870.
I am trying to see if anybody else has ever had this issue. 3 weeks ago we had the oil cooler done, “claims there is no thermostat”. My only question. Wouldn’t a truck with no oil thermostat run 210-215? Not 240-245?. Well that lead to this last Thursday. Jake brake quit working on all 3 stages literally faded down to sputtering and puffing weak, oil temp started climbing again over 265+. Tuesday after I was told it has good oil pressure and to go ahead and run it. I was running down the road and I heard a big clanking sound and a shi#t ton of white smoke that the cars behind me couldn’t even see in front of me. Does this sound like an injector tip breaking off or more of overhaul time? 582,000 miles on. Before anybody asks THEre IS nO TuNE and it is
