A bug in the tuner could easily cause this. A couple whoops injection events, to get fuel in the oil. Or to hurt the injector to cause it to leak on the wrong stroke..... Combine that simple fact with "lightly used retirement truck", and the picture gets worse.
Weve seen minor injector issues, or minor software bugs affecting the injectors, wipe out big 4000 horsepower v16 diesel engines, in no time at all.
Diesels need worked every day, to maintain reliability. You dont have to flog them, just work them. Our trucks that sit, because theyre backup trucks, fail far more often. We keep the gas trucks for that. Auction off the extra diesels.
Should have bought a gas truck. Sorry.
A freind of mine made the same mistake. Tuned a perfectly good truck, and blew it up. Worst part was, he had ordered it with sissy gears. If he would have ordered better axle gears, he would have had more power than the tuned truck. And not killed his warranty.

Problem with tuning is adding advanced timing on the injection event causing extreme cylinder pressure

Meanwhile I had one bone-stock 6.0 with rust being its biggest problem, and one that was giving me issues with injectors before I went through and bulletproofed it and added a towing tune. And my dad is STILL driving his bone-stock '08 F450 with a 6.4 and 300k on the clock. Every one of them either daily driven or used often to tow heavy loads...or both.
