6.7 and general diesel questions

[JoshHefnerX]

Thinking about an f350 w/ a 6.7. The one big thing that's got me nervous on these is the possibility of emissions failures, esp ones that leave you roadside like def faults. Have not run a diesel before.

You guys have a breadth of experience and use some of these in your jobs or related experiences.

Have the def failures gotten better over the years, and what if any experiences have you had.

The DEF stuff isn’t the issue, it’s the fuel system. They are very sensitive and if you’ve got to replace it it’s a $10k bill. Keep up with your fuel filter and water separator maintenance and you’ll be good. They are pretty solid engines. Mine would get 25mpg running 75-80mph. I miss that truck bad.

They are good trucks overall but yes, contaminated fuel system will put em down in a hurry. Always have 10k in your pocket imo.

Thinking about an f350

you had me at 6.7 in the title and lost me at f350

The 6.7 is decent in comparison to Ford's 6.0 and 6.4...but that's a pretty low bar to clear.

Yeah, why a Ford?

I haven't ever owned a diesel pickup, but I have been around quite a few, and heard of the repairs. Yes, I am biased towards GM, but that doesn't mean that they are perfect. I believe that the 6.7 Cummins is a pretty good engine, even though, from what I know, it doesn't have an actual Cummins cylinder head. But I am not a fan of the Ram body and I wouldn't have faith in the wiring or some of the suspension components.

A Ford, no way in my opinion. The things that I have seen people go through with them, the stuff that I have seen on YouTube, the crap that I have heard of from repair technicians, no... way.. The wiring fiascos that i have heard of. A blind spot monitor module will screw up power windows on an F150. The bosses Dad found that out. He cracked the lens on his taillight, didn't fix it soon enough, then it cost $2K for a module and taillight, and he still had to wait a month to get it reflashed.
Heck, I have heard that the dealer here is a month out on all repairs. They have so much stuff broken that they are stacked up that bad! In the meantime, my wife's little Buick had a purge valve goof up. She took it in the day after she called them, they ordered it and she took it back 3 days later and got it replaced. Less then 2 days downtime total.


Anyway, as said by others, plan on fuel system maintenance, I recommend a good fuel additive that adds lubricity. I use Schaeffer's for the fleet at work, my son uses it in his Dmax.

Solid front axles don't seem to be that great in the late model stuff. Ford has a reputation for having death wobble even at low mileage. I heard of it happening at 8K on one F350. All makes need components replaced eventually, more often with oversized tires.
