How about some pictures? Must have hydro locked if the piston was pushed sideways and the liner busted. Sudden injector cup failure maybe? Did you replace the head with brand new genuine cummins?

So I used all genuine cummins parts. But I did have my machine shop reman the head. The head isn't cracked but could have injector cup failure. I didn't pull the cup to see. I still haven't tore it all the way down but I had the rods remanned at my machine shop with new bushings in them and they were within spec. I also used all new cooling nozzles, but the thing with a cooling nozzle is that it should have scored the liner up if it wasn't properly lubed but the pieces of liner that I have don't appear to be scored. I'll get it tore down completetly and update on the wrist pin.
