Hey all this is my first post so bare with me. I have been checking this site out since I was researching my truck (2011 6.7 xlt crew) great feed back and info! Now the bad news, yesterday doing 55-60 mph pulling 7k, truck started to drop in power. I pulled of onto side road and continued to check, huge power loss and tranny skipping about! Drove it home (2 miles) no change. could not make it into my drive which is a small hill. At this time check eng. light came on. Called ford to have it towed. upon arrival of tow truck, I started her up and all was fine minus the check eng. light. Dealer looked at it today and said there seemed to be a wire rubbing that caused the injectors to malfunction? Said they needed to replace all 8 injectors as the were leaking badly! Am I over concerned about this? it seems pretty big to me.
4000 miles truck dies, dealer says injectors need to be replaced

My 2011 is in shop right now geting all 8 injectors replaced so it can happen. I really hope this isnt a pattern for the NEW 6.7
service manager stated that they were all leaking thru. I don't have the first clue what could cause this. He said there was a wire harness rubbing, but I find it hard to believe it would happen in less then 2 months time my guess is some type of glitch in the control modual.
What did they tell you was wrong with it?

I had injector malfunction code then they drove truck with recorder and found #4 injector malfunction. So Ford said put 8 new injectors in it

O im very pleased with Fords action with my issue. My service has been top notch. Ford really wants to help:thup:
Said they would change oil and filter. I too am happy with fords response... Not with the flaw in design though. This is my 4th ford, 3rd sd. and I will continue to buy them they are the tuffest work truck out there. But it is disheartening to here even the service mngr. and diesel teck upset with these problems and the frequency it is happening. I'm sure in due time(fingers crossed) they while hone this beast in. 96000mi. left on the warrenty that should do it!

It will be a couple more years before I decide whether I'm ready to try a diesel again. Monitoring issues closely until then. Good to hear Ford is not messing around with replacing injectors.

I wish they would have done that on my 6.0. Instead they changed them all on 3 trips. the last 2 was my money
I would like to SEE what went wrong, So that I can not make the same mistake again, if it were my mistake to begin with.
Using Diesel fuel Additive is worth every penny in these newer engines with emissions one to displace water and two for proper combustion and three for lubricity of your injection system.
remember the #2 pump supply is less of a lubricant it was 10 years ago, The engine oils have had the lubricity removed due to killing the planet, and the same was done to the diesel#2...
The wire rubbing? Show it to me dont tell me, if it were my truck...

will find out more tomorrow and get the latest. and you are absolutly right. with what you are saying. I will plan to be shown the "rubbing wire", like i said I can't imagine it happening in less then 2 months. and as for the truck I have been breaking it in pretty light. not beating her so any wires rubbing was not from my driving.
got truck back on thursday, all 8 injectors replaced per tsb 11-6-10. Seems to be running well again. 22mile drive home on rt 7. (full of small hills, and few stops 45-50mph) I reset the milage to check it as it had dropped to 14 prior to the injector malf. code, got just under 23mpg on computer! Will keep eye on it, just happy to have it back!
I looked at TSB 11-6-10 (June 14, 2011)
The chafe issue is near the EGR cooler gasket tab; says for vehicles built on or before 5/26/10 to bend the metal EGR cooler gasket tab eyelet rearward flush with the EGR cooler housing. So that must be the rub point.
The injector issue is that gelled diesel fuel might restrict the fuel injector return hose; this is for engines built on or prior to 5/18/11 that get DTC P1291 or P1292; the restricted fuel flow shorts out injector(s) and if found to be shorted they replace all eight plus install new design return hose.

Well... NOT to be condescending or insulting in any way toward you or your comment...
Water dispersers are not allowing the water to regroup in your engine and cause damage. If anything the water molecules will help to clean your cylinders as they become steam at those high temperatures. In the old days we would spray water mist into the intake of the diesels while we held the RPMs at about 1800 to 1900 and the steaming effect would clean a lot of the carbon build up from the pistons. If you read the old car magazines you will even find plans for installing a water injector system on the air intake to make the engine run cleaner and increase fuel mileage.
The reason to disperse the water is because, in its natural state, it will not blend with the fuel. This creates flow issues in the system and periods where it replaces the fuel in the line causing wear to the pump and injectors due to the absence of any lubrication. Dispersed in a much smaller molecular state, water will not harm your fuel delivery system.
The truth is that the additives work and they work well in preserving the integrity of your diesel engine, with the ever increasing danger from EPA regulations that just bring more and more harm and less and less performance to the fuels we use. If you don't treat your fuel... you WILL be replacing parts sooner than later.

that a great theory, BUT it doesn't work. water injection into the manifold is way different than pushing it through very tiny holes in any modern diesel injector. modern diesel fuel filters have a coalescing membrane that will separate the water out. a dispersing additive actually fights that. a water diesel mixture has a higher surface tension/viscosity and doesn't flow readily through the injector tips. then the tips blow apart and you buy pistons head and if you're lucky f up the block too. ps don't bother telling me what you used to do with your grand daddy's truck this is not his old beater and it won't work. that old old load of horseXXXX about lubricity of diesel fuel..... yeah yeah i have been hearing that since i was 10 i'm 43 now.if this fuel has been getting less slippery for33 years it must be damn near grinding compound by now. and even those old 33 year old diesels burn our 2011 non lubricating diesel with few or no issues. the whole lubricity issue has 2 parts, #1 quality of lubricant, #2 quantity of lubricant. eg you could use the most incredible synthetic lube but if your volume is only 20% of spec you will get damage. same for the fuel system most of the 6.0 injector damage comes from reduced fuel pressure due to plugged fuel filters. you could be running 100% additives and if your pressure drops you still kill injectors. that is why everybodys first mod recommendation is a fuel pressure gauge, its that critical

And just what schools have you gone to to say all of the experts are wrong. If you do not want to add anything to your fuel... have at it. I do not care. But you are trying to tell every one else that all additives are snake oil and never needed, Well the owners manual even says that FORD provides an additive to use in the fuel for cetane. If it did not work as it is intended... WHY would Ford sell it under THEIR name from THEIR parts counter? I will use the additive because I have seen the improvement in the engines for friends trucks when they were having problems with performance. They poured the additive into the tank and the problems went away. Fuel is NOT consistent from pump to pump... Cetane levels are all over the board. You don't trust the big additive companies but you trust the big fuel companies. That is YOUR choice. Back when I was running a 903 Cummins across the country... I used a small bottle of additive to keep the fuel from jelling in the winter. I know it worked. It also made the engine run better. You do what ever floats your boat. But keep your sarcasms to your self. I will use what I know works. With or without your approval.

I have NEVER used an additive. And doing so has caused the following problem,
