2011 Ford F550... 6.7L Issues...

[Wingate]

Well, we have six of these trucks, one now has 35K on it and is in the shop. While the final judgement is out, the initial correspondence from the dealership is that it has lost compression in 2 cylinders. According to info I was privy to, Ford had been contacted and instructed them to remove the cylinder head and inspect for damage on the block.

Another F550 that our company purchased after the initial six is at another dealership and according to the e-mail I read, it is suspected of having a dropped valve.

While the jury is still out and final analysis is yet to be determined, it definitely has us paying close attention to our trucks as we drive down the road. . these first six were very early production trucks, so maybe it was isolated to them. I have no idea of when the seventh one was purchased. .

Ouch! If they're looking for block problems, I assume the 2 cylinders down on compression are adjacent? My first guess would be head gasket.
Do your trucks get worked hard, spend a lot of time at full power?

 

[Wingate]

Oddly enough, the repsonse from the dealership is that it is cylinders 2 and 8... they are suppose to have the cylinder head off at some point late today. . Cylinder 2 was verified with a manual compression gauge... not sure about cylinder 8.

As for being worked hard, I would have to say no. . This truck spends almost all its time at Interstate speeds travelling 1 1/2 hours each way every day. . Other than that, it sees some idle time on location. Mine weighs about 20K give or take 1K in parts... and his truck is lighter than mine... . so its definitely not overloaded.

None of these trucks see high load low speed operation... .

Not sure at this point if the other truck is suffering the same exact failure... . or whether its issues are in the same holes... .

I'm trying not to laugh. And as a business owner its not funny.

I saw the underhood of the new Ford 6. 7 diesel and my goodness who'd want to work on that thing. Talk about 12 pounds of apples in a 10 pound bag.

I'm just thankful for my trouble free 2005 5. 9 3500 and 2011 6. 7 3500.

I hear ya. You'd have to be Houdini to work on those things. They should really have a tilt front end. Can they afford another engine disaster in their HD pickups?

Do they have to remove the body?

I believe they did... . Not sure if it was mandatory, but probably easier. . The more seasoned Ford techs. can probably get a cab off of a Ford pretty quick... (6. 0 and 6. 4 experience) They may have done it expecting to replace the engine anyway. .

One good thing about the 6. 0 disaster is that all of the Ford diesel tecs got VERY proficient at pulling the cab. At least the cab mounting bolts are never on long enough to get rusty!!

I have seen one case similar to this on the net, about a week back. Seems it was a tech at a florida dealer , and early theroy was that a glowplug tip had broke and got into the valves. I will have to look back at this, and see if they came up with a final verdict. Monday of this week i went in for a inspection sticker at the local dealer in town. While there i asked one of my tech friends if anything on these new engines were poping up for them at the late. His reply was zero engine issue's to date, a few odd and end sensor type quirks that set codes, and only a handful of reflash type issues for transmission shifting.

That's funny Gonzo, LOL

Was this a 550 with the 300 hp engine or the 400 hp tune???

While I haven't seen the pictures yet... . we heard today that all the exhaust valves on the cylinder head that was pulled have cracks on the face. Some are supposedly worse that others, some of the cracks have "opened up". . and one valve face (presumedly cylinder 2) actually failed and caused the damages. .

I might possibly be able to put my hands on the pictures in the coming week... will see what I can do.

This is starting to look bad... this truck isn't the most heavily loaded, but has the most miles... make us wonder what is in store for the near future. .

Very interesting.



Keep us posted.

Would be WAY funnier if it wasn't so TRUE Maybe the next thing will be Velcro fastners for the cab

As i recall it was an early release 3/4 ton. I do recall the tech saying ford was "all over" the issue with concern. Havent had a chance to dig up the thread, but will make a point to do so today and see if there was a concrete theroy as to what happened. I also plan a trip to the local dealer today to pickup a thermostat. I will ask the service writer if any rumors are floating around about issues of this nature.

Atleast with this being an in-house engine, Ford should respond quickly to get the issues resolved.

What I am hoping for is that its a parts quality issue that has already been resolved and hopefully MY truck doesn't have any defective parts in it. . I hate moving tools from truck to truck... #@$%!

Wingate,

Thanks for providing the entertainment . . . errrr, I guess I am supposed to say the information, not the entertainment.

I'm just home today from a trip pulling my fiver. My Dodge C&C has a little over 99k miles now, all troublefree.

 

[MChrist]

Wingate, now that I think of it, I saw a Ford commercial/video where Haliburton was using the new Ford trucks. I thought you sent in a picture awhile back showing your new truck and it, too, said Haliburton. Am I remembering this correctly?

 

[Wingate]

I'm not employed by Halliburton, although I do lots of work for them. I believe that was "strokethis_07" . I believe he works for Halliburton up north somewhere. I think they got test mule trucks that Ford released for durability testing. .

The local Halliburton yard here is getting new 6. 7L Fords every week... . Though none of theirs have many miles yet.

Harvey... . No doubt. . but I am still hoping that this is an isolated incident related to early production parts. . if not, its gonna be a LONG 5 years!!!. I haven't done any research on the Powerstroke and Ford forums to see if any of the 400 hp. tuned engines have experienced any failures...

 

[HBarlow]

Wingate,

Furd must be nearly giving Halliburton a fleet of those Furds in an attempt to get a lot of them out in service and make prospective buyers believe that they are good trucks because Halliburton is buying them by the dozen.

Time and mileage will tell the story. I predict a disappointing service life. An engine that complicated might be suitable in an Italian Ferrari or other exotic used by some wealthy European playboy to impress his girlfriends a couple thousand miles each year for a year or two until he gets a newer, shinier one.

I don't see how such an engineering nightmare could give anything other than trouble in an oilfield service truck or any other work truck.

 

[Wingate]

wouldn't even want to speculate on the Ford/Halli relationship...



I just came from a powerstroke forum and apparently there are several cases of the 400hp versions grenading the bottom end. One thread had pics of an oil pan and block with a crankcase ventilation door in the side of it... truck had like 1K miles. Ther was another report of an F550 like ours out in Ca. that blew up, but the poster had no specific details as to whether it was top end or bottom end related.
