Wish me luck. 6.4 Super Duty in my bay.

[Wayne M.]

Well, it was bound to happen. I have a company F550/ 6.4 with a no start in my bay. It looks like it had contaminated fuel and now it needs a High Pressure Fuel Pump, AKA their version of a CP3. It's not making 500 PSI on crank. I think it needs 4000.
Yup, the cab is gonna come off. It's buried deep in the valley driven off the rear gear drive. Turbos gotta come off etc etc...
This is a vocational truck with a lot of special equipment like electronics and hydraulics, and a canopy over the cab. Not gonna be like the new shiny blue 4X2 I saw in the you tube....
I won't touch it 'till I get all my parts; pump, 8 injectors and lots of trinkets.

We told 'em to get Dodges!

Have you recently angered anyone in management at your place, or are you just this lucky? :-laf

I've never had the pleasure of working on a 6.4L in a Ford application. Should be interesting to follow this thread with you.

 

[rscurtis]

Bill Hewitt, the Powerstroke Doctor in Atlanta, has a lot of useful videos on that engine. Watch a few of them- you wouldn't take a 6.4 even if it was free.

 

[Wayne M.]

Yup, because it's considered snow eq, they paired me up to get a solid DX on this, so we really wrung it out. Lucky enough to have Ford books and IDS (Fords diag tool), we have it pretty much nailed as the HPFP. All the HP lines, like the ones that split on the Cummins are under valve covers, so even that is not obvious. I can't believe Navistar.

j, were else have you seen the 6.4?

Problem is that at my level, we have no say on what gets bought. I can't believe CAT put their blessing on this engine for marine use...

There are a handfull of Internationals around here running around with this powerplant. I'm assuming they are one and the same.

From what i've been told, IH runs the 6.0 and the 6.4 in some of their own trucks and have very few issues. Most of the garbage parts are what ferd throws at them on the assembly line. I probably wouldn't want a 6.4 but if a 6.0 truck came by at a really cheap price, I'd pick it up and delete delete delete. They are reasonably reliable once you've deleted the problematic emissions components and upgraded the head gaskets and gone to head studs. I'm fairly certain the 6.4 can be made reasonably reliable with the same mods and a good programmer.

 

[jgillott]

The 6.0L or VT 365 was a complete disaster in the International applications like it was in the Fords. The transportation company that contracts with where I work had 25 VT 365 Internationals and not one made it without major repairs. Many had several complete repowers from International before they phased them out and many many turbos, head gaskets, egr coolers, etc. They have a handful of Maxxforce 7's now along with 20+ Maxxforce DT's and they have been real solid to this point.

Looks like the same basic engine. Yes Fords tampering changes a lot of things. I personally wouldn't own one.

Good Luck!!

Just thank the lord it wasn't a new 6.7 since they look as if Gates hose company threw up under the hood :-laf

 

[Gonzo 1066]

When I first saw the cutaway Powerstroke 6.0 (at the time of introduction) I threw up just a bit!! 4 head bolts per cylinder???, come on Navistar, these are the guys that have been building 6 bolt diesel engines for DECADES. Someone really had his head up the rear on that design. The change to the 6.4 lessened some of the mechanical designed in carnage, but is really not much better. We all have to feel sorry for the Ford loyal, they had to suffer one of the worst diesel engines since the mighty General Motors 5.7s

 

[Simplysmn]

Well you know guy's they say 90 % of the Ford's sold are still on the road . the other 10 % have finally made it back home :-laf

 

[DonFitzwater]

If the OP was taking care of a 6.7, at least he'd be taking back to Ferd for warranty. That 6.7 is a nightmare to work on.........................PERIOD! I did the first oil change on mine when I had it and from the first oil change on, it had an oil pan leak at the crappy little drain cock they installed in the plastic oil pan......

 

[Wayne M.]

We have 6.7's too. It's only a matter of time. Lol. Proof that's packed to capacity is that they were forced to put the PTO on the transmission.

1st good laugh of the day and its not even daylight yet.

Wayne,

How 'but getting some Ford decorations for the shop, a blue oval on your shirt, an old Motorcraft cloth fender cover till you get the cab off yuck and about 3-4 bags of speedy dry, couple 1 gallon jugs of GoJo and see who's the boss, Wayne or the curse of the Blue Oval. At least they did circle the problem for you.

Good luck,

Gary

Oh yeah pic's as the cab comes off too...

That's a good one. I'll have to use that in the future.

So let me get this right!!! if contaminated fuel had been ran thru a Dodge!!!! this wouldn't have happened?
Some how I don't think there would be much of a difference, but then again??????

Probably, but the difference is you can change out a CP3 and injectors on a Cummins without having to yank the dang cab.
I have a friend who owns a roadside service repair company for larger class trucks/tractors. He has an F550 service truck that came with a 6.4 in it. He dealt with the engine until the warranty ran out, and yanked it in favor of an old school hopped up 7.3. Too many injector/turbo failures that was costing him alot of down time. Down time means money out of his pocket so it had to go.

If a mech. Is paid by the hour WHO CARES how long it takes to fix the thing. as far as Ford vs Dodge. up here we have about 50/50 and the Fords have nowhere near the drive line problems as the Dodges, Yes the Cummins is the only reason for 90% of us being on this site vs the Ford if they had put in the Cummins. then we would be on a Ford site yapping about the Dogs. being a POS

 

[JR]

I wouldn't want to touch anything that required that much work just to get at simple bolt on fuel system components whether I got paid to do it or not.
As far as being an owner of one of those trucks with a 6.4 or a 6.0, come on out to Ohio. I could take you for a ride around the country side and show you a bunch of good deals with a blue oval on the front. Most of them got weeds growing up around em.
