6.7L Ford Issues...... Round TWO???

[Wingate]

Well... . DANGIT!!!!... Atleast its not my truck... . but it appears as though we have yet ANOTHER 2011 Ford 6. 7L that has "ate a bullet!" Nothing completely definite as of yet since it happened late Friday... But it appears to have the same symptoms as the other trucks we have that failed... . Should find out more in the coming week... ...

 

[Mikey-KE7LBB]

All I have to say is WOW!! I was hoping that they would do better with the new engine, but I'm beginning to think that using the same engine as they do in their medium duty trucks would be a FAR more viable option for their success...



I haven't seen or heard of any trouble with Cummins equipped F-650 or F-750 trucks... Maybe they should go that direction and save themselves from any more future embarrassment!! :-laf

That's too bad for Ford...

 

[MChrist]

I have to assume Ford will find the root cause of these failures and this will become a non-issue.
Since I assume these trucks are F550s, I also assume they are not the high hp versions?

You are correct... . same engine, different turbocharger and different software. Engines are rated at 300hp. vs. the 400hp. pickup tune.

From what I have read, the turbocharger is reportedly one of the same turbos used on the previous 6. 4L engine.

The root cause is either early release parts (valves) that have since been corrected, but we have hear several rumors that its actually a software issue causing certain cylinders to get overfueled and causing extreme EGT in those cylinders... . thereby causing exhaust valve failure. This rumor may have some merit, since our failures seem to have all happened on the same cylinders. Of course, when the valve face detaches at 2500rpm, it becomes a death sentence to the engine rather quickly...

Had the same report as previous failures... ... Truck was running down the road just fine, got a dead miss and felt "unbalanced"... as the truck was getting off the highway, engine kept shuttering... . went into an extreme derate condition and shutdown... . Would not re-fire. .

 

[Wingate]

We heard from the dealership today. It has ZERO compression in a couple of cylinders. I KNOW my day is coming... . ARGH!!!!

 

[MChrist]

Were they the same cylinders as the last engine? I think it was 2&5? If so, maybe it is a software issue...

 

[Yo Hoot]

Ford must have hired those Navistar engineers.

Thats funny right there... . hahaha...

IF its a software issue, there is some good and some bad.....

Good thing is there wouldn't be a massive cylinder head recall for thousands of C&C trucks... . It would be a relativley painless for procedure to fix new trucks on the assembly line and in dealership lots.....

The BAD part is for those of us who have already logged thousands of miles with this condition happening... . I'm sure some bean-counting idiot has already been crunching the numbers and decided if we don't have symptoms of a failure, they will simply dump the corrective software in it and consider the situation closed.

If the engine gets out of warranty before having a nozzle crack or exhaust valve fail due to the extreme heat... guess who gets stuck holding the check????

HOPEFULLY, this is NOT the case.

That's a good one! I believe you may be right.

I think that years ago Ford should have updated their 6. 6 tractor/truck/industrial engine and used it in the PU. With a lightened block and a modern 4-valve head, it would (could) have been a contender. They could have developed that engine for less than they paid in 6-litre warranty and buy-back costs.

What is/was the Furd 6. 6 engine you're talking about? Was it an inline six real diesel engine?

 

[rscurtis]

It was an inline six based on the English tractor engines that were introduced in the mid 1960's. They were made in 3, 4, and 6 cylinder versions. The three cylinders were both gas and diesel engines with the same block and crank, just a different head. These engines were way overbuilt, moreso than the beloved Cummins. The six was used in agricultural tractors and in Ford's 6000 and 7000 trucks in the 1980's. There was also a 7. 8 litre version. It is also known as the Brazilian Ford engine, as later versions were made there.

 

[NIsaacs]

Yes it was a real in-line 6 diesel. I been around them just a little so I don't know much about them. The 6. 6 had bigger brother too, the 7. 8. They were made in Brazil if I remember right, from about the mid 80's to mid 90's.

I know nothing about them but had heard of the Furd 7. 8 liter diesel. Don't think I had heard of the 6. 6.

The Ford 6. 6L and 7. 8L were part of Ford Tractor Operations (FTO). When Ford sold FTO to New Holland, the 6. 6L and 7. 8L and other agricultural and industrial tractor engines including the Brazil factory that built the 6. 6L and 7. 8L engines went to New Holland along with the rights to the Ford blue paint, but not the Ford nameplate. Ford wanted desperately to get out of the farm and industrial tractor business and just about gave FTO away.

[Wingate]

Well, Ford owns Cummings, so why don't they just quit selling THEIR engines to Dodge and start putting them into Fords???... Wait, I read on the internet that its becasue Dodge has some 20 year old indestructible contract with CUMMINGS... I know its true. . I read it on the internet!!. . hahaha...

Sorry guys. . I couldn't help it... .

Anyway... Sounds like they had a good platform for a diesel engine... . but it seems that Ford has always geared toward the V engine configuration.

This was a poor decision on management's part IMO. Ford should have stuck with their core business and kept the FTO and HD truck division instead of getting involved with Jaguar and Volvo.

Not to mention Aston Martin and Land Rover.
