Tell me your horror stories (Diesel)

The bullet proof 6.0 does very well in my experience. I have a few friends that have done the upgrade and achieve longevity. So I consider that expense money well spent if you plan keeping the 6.0. Now if you would ask me about diesels at work then I don’t care for them, and yes we have lots of issues. However to be fair, the 6.7 Ford has done well over the years in service. Not so much with the 6.0 non bulletproof or the 6.4. If I were to own another diesel I would personally go with the Cummins or the duramax. But since I don’t pull more then 10k and not all the time, I can’t justify the ownership of one especially since there’s potential expensive issues with them. I know some don’t believe that last statement but I’m honest enough to say when they break they break and are expensive...... now if we look at the reason why they break sometimes is because of ownership mods or just poor maintenance by the owner. So a lot of times on YouTube and on the net, I watch or read the dramatic horror stories only to realize you always can’t blame the truck but the owner who tunes it way up and role coal.....
