keep fresh coolant and fresh oil and no tuner alleviates 90% of the problems with these... my wifes brother owns a big diesel shop with a ton of 6.0 knowledge, so if it takes a shit on me I do the whole bulletproofing, delete, tuner, studs for about 3k out of pocket. Or I may sell it by then who knows. Btw I still own 2 Cummins powered trucks lol
