6.7 Engine Difference?
Hi all,
I have a problem that I think I am getting the run around on, I have a 2011 F450 truck and it supposedly has big problems and has been to numerous dealers and I finally decided that instead of the 15000-21000 estimates, I thought why not just buy a salvaged motor. So I found 3 different ones and the problem that the guy at the shop is telling me is that there is a difference in the motors for a F250 and the F450 -550. I have heard that one has smaller turbos and different exhaust and all sorts of crap but no one can confirm if and what is the difference.
Anyone know if this is possible or even true?
Thank you in advance.

The difference is between any cab&chassis vehicle vs. standard pickup chassis.
The cab & chassis trucks are debated by 100hp and have different turbos. It's both a hardware and a software issue.

I would guess its a cab chassis.
And as ruschejj says, there is a number of differences, first which is the turbo, then is the programming etc. that supports the different calibrations. You could in theory put a pickup engine in a cab chassis, but you would need the PCM from it as well, and I am not sure how well it would communicate with the rest of the electronics.
You are much better off trying to find the engine from another cab chassis.
Out of curiosity, what went wrong with the original engine? Did it drop a valve?

What went Wrong, well thats a good question as not the original owner, but ford says fuel contamination, and to me that means ok pull the lines flush em out and get back out on the road.
I have been doing some reading and it seems like this is a big problem. so when the dealer said anywhere between 14- 20 thousand I thought for that money just put another motor in it. Than the kicker, they are different motors so my partner and I are now trying to decide what to do with this truck. a lot of dough to throw at it, for a problem that might come back again in a year or 2.
The more things change the worse they get with these trucks it seems.

I would imagine the motor itself is fine. Just needs lift pump, injectors, HPFP, and all the fuel pressure sensors. If you have what it takes to swap motors I would just buy the parts and fix it. Less work and cheaper I'm sure. Somebody has posted a part number for the whole kit to fix this I think it's 5-6,000 in parts. I'd be worried about a salvage motor having a bad or slightly rusty fuel system that could put you in the same boat.

Sounds like your fuel pump grenaded. Yes, it is an expensive repair, your insurance may cover it. See this thread: https://www.ford-trucks.com/forums/1...-warranty.html
Also, the fuel system is the same for both engines, you could buy the replacement engine and swap the entire fuel system.

EC3Z-9B246-A is the part number for the high pressure fuel system kit for this engine that includes HPFP, all HP fuel lines, all eight injectors and such. As I have been told, it does not include the DFCM. Typical labour charged for this repair ranges from 25 to 30 hours of labour. You can inquire about the price of this part from any Ford store across the nation or online, and go with whoever gives you the best price.
BRAINFART. Since you mention this is an F-450 cab and chassis model with the metal after axle tank, I would pull the fuel sender out to see if the tank has delaminated inside. If so, I would replace it with an aftermarket plastic Titan tank and be done with the potential for this problem forever.

If his tank is delaminated and caused the damage, then shouldn't Ford cover it?
Is delamination in the tank a problem with the after axle tank?

The first question, I can't answer but it is a very good legitimate question I'll agree. In answer to your second question, yes.

If or when you do purchase the kit, it would be appreciated if you could post up pics of everything that is included in the kit. By the way, you will need to program each individual injector once installed, using IDS.
