bullet proofing the 6.4?

[macoyle]

So my brother in law and I are way too familiar with the 6.0 and understand how to bulletproof it and all of its down falls, etc. Anyways he is thinking of selling his 6.0 for a job 3 6.4 and obviously we are a little sketchy with it.

We have both been researching and reading tons of threads but I figured this may be an easier route to see what recommendations yall would give for 6.4 information for making it "bullet proof". We are thinking of doing the obvious egr delete, DPF delete, tune and fuel system. What else is necessary and if you could go back and choose between the 6.0 and 6.4 what would yall do?

I wouldn't touch a 6.0 with a telephone pole! LOL

I own a 6.4

I don't know if I would ever pay to upgrade to a 6.4. They can be awesome but my 6.0 is paid for. And one day it may be actually one of the most desirable diesels left (ton built and fairly cheap) when the EPA and federal government completely ruin diesel technology and fun. I wouldn't hesitate to say that us 6.0 owners have it pretty well in the sense that we have the best trucks out of the big three with a pre-emissions diesel engine. It's not the best engine of the three but with a few modifications and a month or two of saving money you can have the best 'all around,' newest, truck that won't be subject to government mandated extortion. I know the 7.3s are loved by many but they just keep getting older and accumulating more miles while many stay away from 6.0s because of a bad reputation and problems caused by the Ford Motor Company itself.

But to answer the first question, DPF, EGR, delete, and a fuel system should make the 6.4 pretty well bullet proof unless you want to build huge power. Many people with just a DPF delete and a tuner can put down 500 rwhp all day as a daily driver in a great looking truck with some awesome interior creature comforts.

the aversion to the 6.0 isn't caused by FoMoCo, it's caused by the 6.0! LOL

the 12v Cummins is the best diesel engine ever offered in a passenger vehicle.

I don't think you can really "bullet proof" ANY common rail engine... All you can do with a 6.4 is delete it ASAP, feed it good fuel, and stay on top of fluid/filter changes

My truck has 1078xx on it and has had almost no issues. Good power, fun truck to drive and FULLY loaded! Whoever thought a 1 ton dually would have leather heated seats, a rear dvd system, nav and power adjustable pedals?? All I've done is tuned and deleted mine and she runs like a top; heck I haven't even done an intake yet. Don't expect great fuel mileage out of the 6.4 though unless you get a tall gear....my 4.30s kill mileage but doesn't bother me.

well our uncle has one thats stock and something happened to where he dropped a valve and ruined the engine, has a new one but thats the only personal experience we have with one of these motors. I know mileage is gonna suck stock but I read all threads of liars getting 22-24 hwy... I think thats a bit optimistic but 17-19 would be nice. The dread is that we know the evil of the 6.0, and have only read the evil of the 6.4 and knowing how much more it costs to fix the 6.4 than 6.0

I'm referring to their use of the gold coolant which causes many common problems and their refusal to acknowledge this. They still put the gold in 6.0s when work is done at the dealership.

The 6.4s are great trucks but expensive to play with, especially if the warranty is up and, for example, the HPFP takes a dump. What if DPF delete crackdowns take off, which wouldn't surprise me in the next few years?

The 6.0 is easier to work on (b/c ppl have been working on them so much) and fix known problems. 6.4s are harder to work on with more complex, more expensive components. Lifting the cab is the first step for many repairs.

well i would never buy a 6.0 again....motor aside,,, the styling of the 6.4 trucks is in my opinion the best looking truck of the big three,and any ford from 1999 to 2012.....do all the standard deletes and you have the most powerful truck of ANY truck with just an exhaust and tuner...then id build the tranny...call it good..
