I buy them all the time. Some are trouble free if left stock and you get rid of the horrid Motorcraft Gold coolant that is the main cause of them failing.
Otherwise, if you do have issues, it takes some money but they can be built to be pretty strong and reliable. And they are excellent on fuel.
Run Caterpillar coolant, stud them, delete the EGR and reroute the crankcase ventilation and you're good to go. But if you don't do that, do not tune them for power.
Note that the VT365 version used in medium duty International trucks never had near the problems the 6.0 Ford version had. Why you ask? because no Motorcraft Gold coolant in the International trucks, and people weren't TUNING their medium duty trucks.
They were probably derated from the factory in the medium duty trucks. They were never built in anything close to the same numbers either so it’s to be expected they had less problems. I’ve only seen maybe 5 used medium duty trucks for sale with a 6.0. I have no idea how many they built but it couldn’t have been many.
