EGR valve for 2007 6.0

[Go Guard]

We have several 2007 F250/F350's with the 6.0 diesel and at least once a week I have one come in for the EGR valve. We remove and clean them, then reset the code only for them to come back next week. We have also went as far as to replace them only to have the same problem. Here's the deal, I am in Iraq and our fuel has no additives in it. When we pull the EGR valves, they are plugged with carbon buildup. These vehicles rarely if at all see speeds in access of 40MPH. Any ideas? Thank you.

Well first off, cleaning is a joke. Ford doesnt even allow us to do it anymore. They will only come back after being cleaned. But when you put a new one in and it craps out is the intake wet inside the egr hole? Also, these motors like to be run, 40mph and under is a death sentence.

I agree but we dont really have a choice at our location. One thing I've asked people to do is to drop it in low and blow it out a little. The intake is dry but full of carbon, although I didn't really pay that much attention to it.

Check next time to see if there is any wettness in the intake, As hot as it is over there especially not going very fast i'm a little worried about the egr coolers.

Roger that, after breakfast I will pull one in the shop and check it out. We were told that it might have something to do with the fuel but the problem only exists on these trucks. Anyway, I will let you know. Thanks for your help.

Let me know if I can help.

Ok, we pulled a truck in that recently had a new EGR valve installed and it too has carbon build up as well as a little moisture going in the manifold. Not excessive but still visible. How dificult are they to replace? Thanks

There would have to be a bit more then a little and you would notice a coolant loss. They are a pain if you have never done one.
