Is the 6.4 as reliable as the 7.3?

Thinking about getting a powerstroke Dually but cannot afford a 6.7.
How is the 6.4? Tell me the good, bad, and ugly.

I'm probably in the minority here but I've never cared for a 7.3. I love my 6.4!

I would also like to get as much info as I can on the 6.4. I am going to be in the market for a new truck and can't decide which way to go. I will be buying a Ford, but can't stand thought of the horror stories you hear with the powerstrokes.

Its hard to tell if the problems are as numerous as the 6.0. I want to know if the 6.4 can me made "bullet proof" with mods like the 6.0 supposedly is.

The 7.3 I had has 377.000 miles on it with nothing more to report than an injector cup leaking. I doubt I will be so lucky again.

No it is not as reliable. This will open up a can of worms but. The 7.3 can be driven in a fleet and kind of maintained and last 500k where as the 6.4 needs some loving to last that long and would need a EGR delete at least too.

So the 7.3 is still king of the reliability and will be for years to come I am sure with the complexities of emissions and electronics. Those will always fail first.

nothing is as reliable as the 7.3 except mabey a 5.9 cummins. the 7.3 is bulletproof alot less emmisions crap to go wrong. honestly i would hate to buy a newer truck and still have to do headstuds and egr deleate and do away with the reburn just to get your fuel milage back and to make it somewhat reliable.

maybe a 5.9 Cummins?!?! LOL Sorry, but the 12v Cummins is arguably the best, most reliable engine ever offered in a passenger vehicle.

The 7.3 has CPS issues, a Rube Goldberg designed HEUI injection system, potential cavitation issues, HPOP issues, cold start issues, etc. etc.

the ONLY issue a 12v has is the KDP. you can nix that issue from every being an issue with an hour of labor and a tube of silicone.

no need to do head studs on a mild 6.4. no real need to do EGR delete if you just run a delete tuner early. dpf delete takes no longer than installing an aftermarket exhaust on a 7.3.

the 6.4's will start in the cold and have a beast of a transmission. arguably not as reliable as a 7.3, but power-to-power, they're pretty decent. hollar at me when you have a reliable 7.3 making 450+rwhp and let me know how much money you have in it.
