I have an 03 6.0. Engine was replaced under warranty in 05, turbo replaced under warranty sometime in 03. I bought it in June of last year. Shortly after I had some injector issues. I replaced them all when 3 or 4 went south. I got 8 used from an 05 for $400. I believe the issues that I had were most likely due to maint or lack there of by the previous owner. I love the thing and wouldn't think of getting rid of it. Not at this point anyway. It's like a sports car inside a truck body. The 7.3 is pretty bullet proof though.
