I have a 6.0 and couldn't be happier. back flush the coolant system and keep up the maintenance ,most of the bad talk is from people that never owned one. Do you own one Josh?
Two of them, actually. The first one was a total mistake. The 2nd one I bought already had it's motor blown, so it got a 12V Cummins installed within a week of purchase.
While working at
Beans Diesel Performance, it'd be safe to say that 90% of trucks that came in with problems, even stock, were 6.0L Fords.
Sure, there are some owners that swear up and down that their 6L is great. But those that barely got 50k miles out of it, then had to fork over $5K+ in repairs, will swear, swear, and swear some more.
