I finally got fed up with my 6."Oh-No!". After this last go-round of the typical 6.0 problems which in the last 3 months have included an EGR valve replacement, a possible FICM going bad and definite injector problems either related to the injectors themselves or the HPOP, I decided to trade my 2005 Excursion on a 2010 F250 Lariat.
The X has just become 'possessed' for lack of a better term. It's at 122K and aside from engine issues, there are several electrical issues going on with it as well so it was just time to say goodbye.
In fact, after living the 6.0 nightmare (in spite of regular maintenance, 0 mods, running cetane, etc..) I'm surprised to find myself back in another Ford PSD. I was dead set on a Dodge Cummins, but the 12K I got knocked off the last 2010 Lariet CC the dealership had and the comfort of a 75K bumper to bumper that I got them to throw in was enough to sway me.
So far from what I've been reading it appears that the 6.4 is shaking out to be a pretty good engine except for some early issues with the Build 1's from 2008. I accept that the mileage isn't as good because of emissions, but is the 6.4 good enough to atone for the sins of the 6.0 and what do I need to be on the look out for. Thanks!!
BTW, it's my first post here - been a long time lurker though. Great Forum!!
