Wife and I decided to sell my beloved 7.3 Excursion so we can upgrade our travel trailer to a 5th Wheel. I have only driven a 6.7 once and It was a rental that my body shop paid for, so I abused the heck out of it. Love it. Just wasn't thrilled about the DPF fluid.
My budget is only going to let me look at an 2011 or 2012. Looking for a CCLB 4x4, preferably King Ranch or Harley if it was available.
Are there any Pros and Cons for either year?
Thanks
Until mid 2012 they had a couple of issues with exhaust valves. Basically the valve would bend/break/mess up and fall down into the cylinder; breaking the glow plugs along the way. Cycle some metal around in the cylinder for a bit and suddenly you need a new engine.
They looked the problem up and attributed it to quality control. Re-did their procedures and it went away. They also reworked the depth that the glow plugs reach in to cut back on glow plug damage.
Early 2011's had issues with the bearings in the turbos going out. Again, quality control issues.
FWIW; remember this is Ford's first run at an in-house diesel (to my knowledge) so it was honestly a rather mild learning curve. They've responded well to the issues brought up.
If you buy a truck with a few miles on it (75k +) then odds are if the problem was going to be there then it would be there. If its not a problem then you probably got an engine that is good. If you're getting one with real low miles I'd actually be more concerned (unless it was pre-owned with warranty kinda situation.) Of course the other option is to spend a bit more for a 2013+.
New turbos started in 2015. But the new turbo fits in the earlier editions as well.
All of these trucks have issues with the fuel system having water in it. It's less to do with the powerstroke and more to do with the pump; Bosch CP4. The older diesels ran the CP3 which used oiled bearings. The CP4 relies on the lubricity of diesel to keep it running smoothly. Water doesn't lubricate as well as diesel and if you get water into the CP4 it will burn out and "grenade". Shrapnel from the bearing system runs down the high pressure fuel lines and compromises the walls on the way. Then it hits the fuel injectors and tears them up. So you end up taking out the CP4 and ripping out everything till you get to the injectors.
The CP4 is the new thing for diesels; all of the little diesels use them (VWs, etc.), the new duramax, the 5.0 cummins, etc. The 6.7 cummins still uses the CP3. To avoid the CP4 turning into a grenade keep the water out of the diesel. I added a Racor 500 fuel water separator before the ford OEM one. Most people prefer the baldwin 100 on ford forums. The racor is very similarly designed and is more popular on marine forums; I figured they knew about fuel and water so I went with the racor. You can also run extra lubricating additive.
Thanks for the information. I also like Racor since I work part time as a mechanic in the marine industry (Getting them at dealer costs also helps). I also really like the DieselSite fuel filter they sell. I have almost everything DieselSite makes on my 7.3 and have been to their shop a few times. They are awesome guys that do a great job. Have never had any problems with their products
As far as the Turbo and Injectors go, the factory ones will not last a year in whatever truck I get. I will quickly upgrade both because I am never satisfied with anything.
No need to change the injectors on a CR engine, unless you want A LOT more horsepower.
