I parked my RV for the winter and the storage owner liked my 2008 F350,started to ask questions about it. I mentened to him that I have test driven a new 6.7 and I liked it, he mentioned that a friend of his is a diesel mech. at a local dealer and said that he is doing a lot of repairs on 6.7 turbos. Just wanted to know if you all have any problems or knowledge of.

 

I haven't heard that it's a common problem, but myself and another 6.7L owner have had our turbos replaced because of a noise they were making at idle.

Otherwise it drove just fine, the noise was simply annoying. The 6.7L has proven itself so far to be a VERY reliable engine.

 

I read somewhere that the turbo wastgate rod was improperly adjusted on some trucks and there was a recall to fix this.

 

There have been a handful of turbo issues in 100000 delivered trucks... his mechanic buddy must have had them all...A Ford engine design engineer was here for a while and speculated that the noisy turbos were the result of tolerance stacking. No harm, just noise. He did say that Ford was replacing these functional but noisy units.

 

Good to know that ford is stepping up to the plate. They have everything riding on this motor.

 

Mine is in the shop now on its' third turbo replacement. 1st @ 34K, 2nd @ 49K, and now @ 77K.
Mine is a 450 cab/chassis with the single phase turbo. I was at dealer today checking on it, and discovered last two episodes did not include replacing the "Charge Air Cooler" (done at other dealerships while broke down out of town). So this could have something to do with repeated failures.

 

Anyone have any updates, I have a 2011 Ford 6.7 Diesel, noise at idle when it's first started.
Dealer calls it a turbo hoot, it started little over a year ago, around 13,000 miles, now has gotten louder, but stops once warmed up, can't get dealer to warranty it, says its normal, but is suppost to have factory rep come and listed to it again.
Any advise would be appreciated.

 

I've owned a 2011 and 2012 6.7 totaling about 45k miles use.
The newer truck has been more solid but neither stranded me or required major service so far.
The early model (9/2010 delivery) had that loud intermittent hoot. However common it is, it can't be normal. The '12 is noisy when cold, a constant whine that sounds normal (cold turbo, running rich at high idle I guess).
Both trucks seemed to make normal boost in all conditions FWIW

 

Ok, thanks! I agree, this noise is just too loud to be normal, can't wait for the rep to come out for a re-check.

 

When cold, I call it the owl sound.
Mine has done this since the first winter and it's a May 2010 build.
I have other turbo noises too but it still produces 21 PSI 43,500 miles later.
Unless it sounds like a table saw, it probably won't get replaced.

 

Does the "hoot" only happen one time after you start it? Or does it keep hooting till its warmed up?

 

It continues to have the hoot untill it gets warmed up, it's too loud, it can't be normal.

 

Well the factory rep came to the Dealership this past week and listed to the noise, and the master diesel technition also, they both finally agreed the noise wasn't normal, so they wanted to start the truck again late day and early morning when it does the noise to hear it numerous times, and they did.
Then they ran some other test, changed the grade of oil, still no change, noise still there, so they have ordered a turbo, should be in in a few days.
Will see from there.

 

im curious, can you make a video of this hoot?
