I was just reading that the F 450 and 550 6.7L Scorpion engines have an issue with burning up exhaust valves. The report said the problem is thought to be that the 450 and 550 models do not have a pressure waste dump on their turbochargers like the 250 and 350 trucks do.
Anybody else heard anything about this issue.
Yes. First hand experience. I think it is due to a combination of things. First being there was an issue with some of the valve stems not being hardened correctly when made in the first generation engines. Second is due to the way the EGR gas is introduced back into the engine, pointed directly at number 5 intake valve. Totaled the engine at 102000 miles in a 2011 F550. Ford would not warranty it. $20K+ to replace it.
WOW!! That would suck. Knowing some friends with first hand Powerstroke 6.0 issues steering me and many of my friends to the Dodge/Ram Cummins combo!
