I seen something come in the shop today that totally blew my mind and I have never seen before. It's a 2008 F-550 6.4 bone stock, with almost 500,000 miles on it and aside from regular maint. it's never been worked on. i'm going to take a picture of the instrument cluster and post it here just to show you. It needs an injector.and the guy who owns it was upset that it was broke down. wow, he has no idea what upset is when you own a 6.4, I have seen 6.0 litres with 190 k on them that are virgin although it is rare i have actually seen them.
