I did the mods when I bought the truck to hopefully prevent this sort of thing, although I had no idea that the 6.4 was splitting pistons. As no luck said, the truck had 110k km on it when I bough it. The regen was horrible so I did the mods hoping for a long lasting motor. Now I am trying to figure out what to do. 16k roughly for a short block with 5 year warranty assuming all my parts didn't get damaged in the blow up. Last ford I ever buy. Maybe last diesel also doesn't make sense unless you tow lots
