A friend of mine said the 6.7 Powerstroke is the worst diesel ever. I’ve mostly heard issues about the first-gen 6.7s, but I’m curious what you all think. How many miles are you guys seeing on these? Are they really that bad? From what I’ve read, the 6.0 seems way more problematic.
There are a ton of happy 6.7 owners out there. Once the first-gen bugs got sorted, they became great engines. Pretty common advice though—never buy the first version of anything new.

Yeah, that makes sense. First-gen usually needs time to get the kinks worked out.

Sounds like your friend just trashes anything he hears a single bad story about. The 6.7 has been in production this long for a reason.
That’s what I asked him—if they’re so bad, why are people still buying them? He couldn’t really answer. He kept saying videos only talk about how terrible they are, so I sent him one about a 6.7 with a million miles. Pretty sure he’s just being biased.

Costs vary. A new pump from Ford is around $1,500. If the system gets contaminated, though, you’ll need a disaster kit—rails, lines, injectors—which can run $5k-$6k. Add labor, and it’s $3,500-$4,500 to replace just the pump or over $10k for a full fuel system.
@Kerry
If the pump fails catastrophically and sends metal through the system, it’s over $10k. Ford stuck with the CP4, while others moved back to the CP3. Big gamble.

Look up the DCR conversion pump. It’s not just a redesigned CP4—it’s a completely new pump that can’t fail catastrophically. Costs less than $3k and pretty easy to install.

I’ve got a 2011 6.7 F450. Just keep up with maintenance and delete the DPF and EGR if you can. Mine’s been great apart from an early turbo replacement and some small leaks. Straight pipe fixed a lot of the DPF issues.
