Whatever you find, just make sure you can 1000% verify the mileage.
MANY times a week we get cars & trucks, gas & diesel that the mileage has been moved on. On pretty much ALL manufactures.
Now, as techs, we can pop the hood and usually in two seconds verify that the mileage is incorrect. I know you're no spring chicken and can most certainly do the same. But im telling you, just BE CAREFUL. These bastards are slick these days.
When it comes to diesels in our shop, the bossman has the knowledge and therefore does 100% of the diag. If it comes in my bay, at that point, i'm only a parts changer.
We tend to get atleast 1 fuel system a week on the 6.7 powerstrokes. Last weeks victim:
Generally, its our farm accounts that have the most problem with these. They all run aux tanks in the bed and at some point they get a spec of dirt or water or some other bs in them and shred the injection pump. When this happens, she'll put metal through everything, even alllllll the way back to the tank.
And not being a diesel tech whatsoever, I now get ahold of the duramaxs, and moving around the fuel system you can clearly see a strong resemblance between the two. We don't get too many of the 6.6s but they do come in one a month or so.
I aint done or seen a 6.4 in atleast a year. We did floods of them years ago. Then they all went away lol. Ford knew they done f'ed up.
I would agree with most that cummins got it right. The engine is soild. The truck it is put in can be another story. We do a couple turbos a year on them. They're vgt style turbos and what we usually see is the unison ring seizing from carbon build up. On your own unit one can sometimes pull her down, clean her up real good, and get some more time out of it. But generally it just gets a turbo. And a few times a year we get one with a puking timing cover seal. For whatever reason, cummins decided to make the camshaft gear one with the cam therefore you have to remove the dang cam just to reseal the cover. I did learn a trick from a cummins feller that involves wooden dowels so you can leave the valvetrain where its at just pick the lifters up off the cam. Victim from 3 weeks ago:
And of course, who could forget the good ole 6.0s. You'll hear endless amounts of bad things. But truthfully, once you get them right, they'll stay with you quite a while. I think we've fixed most in our Hinds county area therefore, we don't see too many these days. We stud em, give em the updated heads, bulletproof if you will, and they're usually good to go a while.
Good luck with your search sir.
