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

[HBarlow]

I was discussing this with my son the other day and he told me to go to "powerstrokenation.com" and look at the 6. 7L Technical thread. There are several document issue with the new 6. 7L Ford engine. One is labeled 6. 7L carnage, which shows a burnt piston, bent pushrods, and a glow plug tip broken off.
What is funny about this is the way the poster was attached by some of the readers of his post. The guy is a ford mechanic at a dealership and they attached him for showing this on the web site.
There is another report of a tubo failure on a different thread.
I think Ford may have another serious issue with their diesel engines in the making similar to the 6. 0L engine.

I haven't been there in five years or more but several years ago I used to visit the Furd powerstroke website once in awhile for entertainment. The website members were outraged when someone reported problems with the junk Sick. Ohh engines. They accused the poster of being a phony making up false stories, even demanded that he post his VIN as if that somehow proved he was legitimate.

Furd defenders are insane. I don't know any other way to explain their mental condition. I guess they believe so fervently in their Furds which occupy such an important position in their insignificant little lives that they simply cannot bear to believe the product is a failure.

It must be like learning that the earth is actually flat after believing the text books and space photography all your life showing it to be round.

That's crazy!



I also still can't beleive they still use glow-plugs!

Glow plugs are more common in DI engines than you think- Cummins is one of the few that doesn't use them. I had a '96 Mitsubishi FE truck that had them, they only worked below freezing so they would last a long time, and the truck would start instantly at 0* F. AFAIK, all the new automotive diesels use them also.

I dont trust that engine... (the ecoboost) the commercial talks about how they have "piston cooling jets, we got 'em, others dont!" Only reason for that is to try and keep those boosted pistons from gluing themselves to the cylinder walls. . Tells me they are running a ton of boost to try and flatten the torque cureve while attempting to maintain emissions... Would seem that longevity will naturally suffer if the little engine stays boosted up very often. .

Just my . 02...

You are correct. This is another situation for Ford where they use an excessively complicated engine for a mundane task where a simple pushrod engine would work. We're talking a PU truck, not an Indy racer. I wonder mow many F150 owners would opt for the old cast iron 300 six if it was still available.

 

[JUeckert]

That's true but why would a business that depends on their trucks to perform their mission buy Furds? How deep must the decision makers heads be buried to be unaware of Furd's track record since 2002?



The company could have bought a fleet of Ram 5500s which have now been in service with a proven engine, transmission, and chassis since late 2007.



Cummins didn't experience catastrophic engine failures when they introduced the 24 valve engine in 1998, the HPCR engine in late 2002, the HP HPCR in late 2004, or the ISB6. 7 in late 2007.



I wouldn't drive a free Furd. I have a serious aversion to walking home in bad weather after being stranded on the highway with my fifth wheel hooked up.

Still got them blinders on i see. Perhaps you never had to see a 12v with a broke cam, or better yet had to pay to get one fixed like i had to. Then there's the dowel pin that many are still unware of, wonder how many had to eat an engine for that one. What about 24v engine's with "53" block's. What about common rail's with dropped valve seats? Never walked into a dealer and witnessed any of those either, have you? Or maybe a failed injector that scored a cylinder quicker then you can say dont. No you havent even dealt with the fact that these are all problems that have happed to the cummins engine of the years. Kinda like the fact that many 6. 7 cummins are giveing a lot of grief over emissions. Get over yourself harvey, they all can, and do break. .

Ford was the only one that Obama and friends did not bail out. At least they are trying. buying aGMC or Dodge is putting money into Obamas re election campaign. ford is doing it like a business should and I hope that these cases are not the norm. I own aDodge because of the cummins. if Ford used the Cummins I would buy one tomorrow.

 

[AClayton]

I am going to sit this one out because I like Harvey... ... ... BUT, as much as Powerstroke owners defend their trusty Fords, he will defend Dodge just as blindly. They all have their specific quirks and the 4th gen trucks seem to have them mostly worked out..... with the only exception-fuel economy.

JUeckert, all the maladies you mention are true, but are statistically insignificant compared to some of Ford's problems. You might have a Cummins with one or more of these problems (if you owned enough of them), but some type of failure was a virtual certainty on a 6-litre.



One of the reasons Ford did not need a bailout was that the billion $ cost of warranty and buybacks on the 6-litre put them into financial straits while $ was still available in the capital markets.

You are exactly the kind of Furd defender I was thinking of when I wrote that.

It's about percentages! No man made product is perfect. For every Cummins engine with the problems you mentioned above their are several thousand of each with no problems in high mileage heavy service.

Try defending your Furds on the Furd website where somebody gives a xxxx.

Not sure what the "official" report will show as to why the failure happened, but this particular failure was/is not due to a glowplug breaking off. I heard that the repairing dealer is sticking with that story, but from looking at the pictures, thats not what happened. If glowplugs were THAT fragile, engine manufacturers would have quit using them 50 years ago. It seems that glowplugs mysteriously breaking off get blamed for lots of failures. Very rarely would a glowplug ever break off without something hitting it first...

This failure was due to valve face failure. . as evidenced by the crack in the valve face on the non-wrecked cylinder.

Im gonna try and blow that picture up so that the crack in the non failure cylinder can be clearly seen.

You got that right, you were likely thinking of me when you made multiple post about fords. I wish i could say i was flattered, but considering the source i really consider it sad. Post after post of your sometimes complete misinformation, based on info you seem to get out of a cereal box. Try getting some of that info from real experience before you shoot your mouth off, and then resort to attack mode when someone points out facts. Your little bleeped out cuss word proves my point. I give you real world experience, and what i have seen on the job sites and shop floors. If that hurts your gentle feelings about whatever brand, too bad. . You can start your little 6. 0 tirade now, but again let me remind you, we are on a different subject. The 6. 7 FORD diesel.

Good call, from what i can see of the pictures. Cracks are weak metal designs, high temps, or high cylinder pressures. I have also seen starting fluid usage do this on some engines. I cant see a gp doing anything but the chipped valve part. In all my years of owning and working on light through hd diesels with gp's, i have only seen one actually break off in usage. A broke gp in one damaged cyl, would not explain the cracks in the other cyl either.

Hers one more... Block was not repairable. .

That had to make quite a racket!

You flatter yourself if you think I think of you. I would not notice or care if you fell off the planet. It is you who attacked me by name. I did not and have never mentioned you. Perhaps you are overly concerned about me?

You don't like what I post or me personally, that's your problem not mine. Your so-called real world experience, like your opinions and defense of lousy Furd products, are of NO value to me.

Yes, I noticed this is about the new Furd 6. 7. Different engine, same problems. Defend them if you wish. I consider them junk like the Navistar Furds were and are.

OK... been trying to blow this pic up so that the crack can be seen. . IF I get this done right, it will be a pic of the NON-warzone cylinder. .

 

[AH64ID]

That crack is pretty obvious.

Was the cracking on the valves only, or did you find any between the valves, valve seats?

 

[gtoli]

WOW!, That's not what you want to see.

 

[Wingate]

Yes, the crack is on the valve only... The valve seats appear to be intact. While we are hoping that its an early release quality control issue. One can't help but wonder that maybe the emissions control strategy may be playing a significant factor in the valve fractures.

By altering injection rate, duration, and timing for emissions... . it would seem that it could very well add more stress/heat that initially anticipated by the design engineers. I don't pretend to be smarter than an engineer... just thorwing out possible scenarios. .

You don't deal with a lot of MBAs, do you? My only possible response to SO MANY of the things my MBA overlords did and said was, "That MBA degree sure must make him MUCH smarter than me, 'cuz I can't see any way in hell that's a good idea. I must just not be smart enough!"



I was the transportation & fleet manager from 1998 - 2006 for a company that had a lot of diesel pickups, mostly Fords. We had pretty good luck with our 6. 0s, but went thru a lot of transmissions. We had a few Dodges, each of which had a good dose of the trans/brake/suspension/misc troubles we all know about. We had just a couple of old 6. 5 GMCs that had held up pretty well, considering their age and abuse, but upper management had a bad taste from the last time the company had a fleet of GM products.



I wanted to get away from the Fords in 04-05. Didn't want to stake my reputation on the Dodge truck. I recommended GM. Whether TDR members agree with that recommendation or not, I had years of experience in auto service, as well as a lowly Bachelor of Science degree in business. Those MBAs who probably couldn't check their own oil shot me down quick as can be.



I hate that the service guy with the broken truck may get a day off without pay, but the damn MBAs deserve what they get! (no offense intended to MBAs who don't have their heads up their ***** - BTW, is your company hiring??)



How about this - present your MBA with a choice to buy a $150K piece of equipment. If things change and you don't need it after a couple of years, it will have solid resale value. Or, you can rent the same equipment for $100K per year, and if, as predicted, you continue to need this equipment for more than 2 years, you can just flush $100K per year down the toilet! Guess which choice my MBA made. I'm just not smart enough to understand why that was a good choice.



I hate to see the 6. 7 Fords blowing up. It's no good for anyone.

We all can only hope that this is a isolated incident or two. It would be a bad deal for this country if Ford had another clunker at this time e NEED all 3 of the Big 3 producing and competing world wide. USA's economy depends on strong US based manufacturing Ford being one of them. Having said all this will I ever own a Ford truck?? Hell no. I have had 5 Cummins Dodge pickups they all have pulled hard for a living. They all gave excellent service and trade in value. My local dealer backs me up on the VERY few times I needed dealer service. Why switch to a trial engine. IMHO
