6.0 or 6.4? what do you guys think

[navistardiesel]

hey guys i know ive posted a million different times about getting a ford, but now it seems im getting closer. im looking for a late 7.3 lariat or xlt 6 speed. but im finding real nice 6.0s and 6.4s that are similarly priced. should i go 6.0 or 6.4, i know i posted this in the 6.4 section but id like to learn more about em and their reliability. should i get the bpd egr coolers for it or do an egr delete. im gonna tune it and do a dpf delete if i get one. any input from 6.0 or 6.4 guys is appreciated. thanks!

I would say it is luck of the draw. If you could find a 6.0 that has the problems fixed may be ok . I am seriuosly questioning the reliability of my 6.4 seems to be one thing after another lately i do have 128,000 on it but looks like it needs a motor now. Just had 1000's of dolllars worth of front end work.On my 4th radiator. On the other hand there are quit a few guys that have had limited problems. I just think you wont see many 300,000 mile 6.4. I also do not beat my truck to death and it sees regular maint short of the trans filter.

really, after reading up on the 6.4 a little bit it seems like people had some serious problems or only minor problems with job1 trucks. coolant leaks and all that and some people had injectors completely wash out a cylinder. other than that, and some DPF related issues which are common i heard the job3's are alot better.

Well the injectors sticking I believe is more of just a 6.4 thing. The job 1 had head gasket and radiator issues. I was just at the dealership today and they ha an 09 that had a melted piston.The job 3 really is the job 1 with the issues supposedly fixed or so I understand it. The job 1 s should have had issue taken care of by now. The thing I dont understand why dont these engine do a better job of protecting themselves.If an injector sticks open why dont the damn thing go into shutdown or something.My dealership told me they have changed way more motors in the 6.4 than they ever did in the 6.0 To me a diesel should run 250,000 or better before you should see any issues.

yeah i hear ya on that, the more techs i see on there say that the 6.4 is quite a bit better, and that theyve made their living on 6.0s... but i hear ya, my 01 dmax hasnt seen a problem in the 8 months i had it and my dads 03 cummins never had one issue

If i had to do it over again i would find a nice low milage 6.0 and do studs and an egr delete. The 6.4 is alot nicer interior wise but a 6.0 that is fixed is going to last longer, and not have the fuel system issues that a 6.4 can have. One other big plus for a 6.0 over a 6.4 is the epa and dpf delete issues.

What is your truck doing that makes you think you need a motor?

Well The cooloant degas bottle puked oil all up and down the side of my truck and motor(hence the only way I noticed something wrong)I figured head gaskets or oil cooler but then I pulled oil filler cap it is a sludge mixture of oil and coolant (thicker than pudding). Currently sitting at Ford. They are suppose to pull it apart tommorrow. They said if it need engine that is around 14,000 but i have yet to check around.

I had a 7.3 that was a 02 and i loved that truck. Ran strong but tranny sucked, HPOP sucked, injector wiring sucked, ball joints went out more then once. Needles to say i have had some issues with it.

NOW i have a 6.4 and it has been a great truck. I have 190,000 miles on EVERYTHING and it runs great and strong. It is just now sounding like a pulley is going out but that aint no big deal. My tranny is strong and i run the spartan 300 as a DD. I have ran the 310 and raced it ALOT against other trucks. I love this truck and i would never get rid of it.

No matter what you get you might not have any problems and you might have some. You can never tell.
