Are the 6.4L's that reliable?

[SJP1809]

Ok I considering trading or just trying sell my current truck (06 LBZ) and getting a 6.4L. I just joined the site the other to research them and I'm getting mixed reviews on what I've read so far, some very bad and some good. What are some of the biggest concerns with the 6.4L besides the fuel mileage? I've read threads about injectors failing, leaky radiators and some other stuff. But I've also read were people have had very good luck with. Can anybody shed any light on this subject before I make my decision on what I want to do??

Once you get rid of the emission stuff and the DPF yes they are reliable and also try to get a job 2 or 3 truck.

I have an early build Job 1 (picked it up 5-07). Never had an issue. Had the T valve put on for the radiator when the TSB came out. Only issue I have ever had with the truck is the AC could be a lot better and the headlights are terrible. (Might add in, whoever designed the location for the lower fuel filter should be fired.)

Truck has pulled and hauled everything flawlessly.

i have 102k miles on my 08 job3 and the only issues i have had with mine is that i have had 3 coolant leaks, none from the radiator (this was replaced under warranty before i bought it) all the leaks were just from minor hoses and o-rings going out. really minimal compared to some other vehicles out there, but i love my truck and i feel that it has at least 300k in her now that i have deleted all the emmisions bs

Mine is a really early one as well mfg date 01/07. Get rid of the emissions and keep up on maintenance and chances are you will be very happy

I haven't owned mine since it was new but I did buy it from the original owner. it is a job 2 with about 83k on it. He ran with it stock and never had it in for any problems, I checked and verified this. I have not had any issues either but the first thing I did was get rid of the emissions stuff.
From what I read its a bit of a crap shoot, if I were you I would look for one that has slightly higher mileage with a lower service rate (not talking about maintenance items, but repairs rather)

I went into my purchase knowing that it has been problem free for a lot of its life and with the preventative mods and good history it should remain that way.

I also think they are a lot nicer of a truck with better power for the money, so even if I did have to throw a little money at it here and there its ok, not that i want to but I figure the fact that its the nicest truck out there is worth a few thousand

Dont let these guys with modified trucks scare you, stock they are fine too and haveproven 200k miles too. With all the epa talk lately be careful.

Well these are alot better reviews that I have been reading. It's still a toss up if I want to get rid of my dmax, so keep that feedback coming guys. I apperciate it.

Not trying to scare the guy man. But it's the truth that you get rid of the DPF and the emission stuff you pretty much have a bullet proof engine as long as you keep up with the maintenance and not beating the crap of the truck with high tunes.

I'm a big Cummins guy. I've had 15 dodge diesels. And the 6.4 was/is good enough to get me to defect to the dark side. Get an Oasis report, check the engine hours to make sure it hadn't been idled to death, and go for it!

I'm still scared of this thing, but MAN does it run awesome
