Re: 6.0 turbo failure

No, it cannot.

Tell your dealer to READ the "Magnuson Moss Act". When they are done, and can understand it, they will have to PROVE that a modification CAUSED the failure, not contributed to it, but was the CAUSE.

First off, the EBP sensor is BEFORE the turbo, no modifications AFTER the turbo will affect the EBP reading because nothing was changed there.

Secondly, reducing parasitic exhaust back pressure will only HELP the turbo respond quicker under near-full boost. The small decrease in restriction is only "seen" by the engine near peak exhaust flow (power). The faster you spin the engine, the more exhaust matters.

Turbo speed is a function of engine displacement, RPM, power output and overall efficiency. You did not alter ANY of those things.

Re: 6.0 turbo failure

[ QUOTE ]
I went through the same crap a year ago with one particular dealership and FSE...saying the same thing.

So, I asked them for the operating specs of the engine which they did give me, went out and grabbed my laptop installed with the Auto Enginuity software and showed the SM,FSE, and Tech that the BP was right in the acceptable range and to quit screwing (not the word I really used) around and fix it. They reluctantly did.

They kept saying that there was zero back pressure!?!?

[/ QUOTE ]

I had the opportunity to hook an AE up to mine as well. With my full turbo-back exhaust, the EBP was reading dead on the money with what Ford says it should be. That clearly showed me that the aftermarket exhaust has no effect on the EBP's sensory readout.

I do think I would take 4x4Mark's suggestion though, and check the EBP. There have been several cases of it going bad and causing turbo related problems.

BTW, I have yet to see any significant correlation to the number of vanes in the turbo and the number of turbo failures, so I don't think that is an issue.

the most common source for turbo underboost is the VGT. either the turbo itself has seized (vgt) from lack of use. By lack of use I mean if the truck is babied and maybe sits for a long period of time. These things like to be drivin the crap out of. Or the VGT solenoid is acting up. EBP is also a cause but no more the ther vgt.

I'm knocking on wood here because I have 170k miles on the same turbo with a 4" turbo back exhaust thats been on there 3 days after I got the truck in 03... Dont think the DP exhaust is your issue. (this is with the stock air cleaner)

I live in a county of 5000 people and their are probably at the moment 10 6.0L's running around and three of them have had turbo's replaced. Pretty crappy odds if you ask me. Take your truck to a different dealer. If your really worried about it put teh stock DP back in and cat. The cat is more important than the down pip from what my tech has told me. The big reps look for a cat more than a piddly downpipe.

I Would Like To Know Why After All The Problems Ford Is Have With The 6.0 Turbo(engine for that matter) Know one.... Has Come Up With The Answer On How To Fix IT The Right Way.... Ford Won There case Against International and We As The Buyers Have Lost hmmmmmm...
Ford Has Every Excuse I Know OF Why We are Causeing The Problem,Well They Tell Us That when we Go There To Have It Worked On,Never Ford Problem..... We All Got Screwed From Ford
I would lIke To See Ford Stand Good For Every 6,0 They Sold as long As Your The Original Owner That Is.....Or Buy The Piece Of **** Back

And what does this have to do with the actual thread that was 4 years old then dug up, then a year old and dug up again and now almost another year and dug up again?

I think one of the updates most of us got had the EBP sensor input only assumed on completion, but I have been told I was wrong before.

180,xxx hard miles with the original turbo! i have a mbrp with the cat gone and just a muffler! A larger exhaust does not lead to turbo failure, if you baby your truck or park it for a long period of time carbon tends to build up causing them to corrode! I say every once in a while put your foot to the floor and hear the most amazing diesel v8 you will ever hear! Cleans the turbo a bit and these motor loves to be driven hard!

06 ford powerstroke 2"inch lift xd series dick cepek fc2 w/ sct custom tunes, 4" turbo-back mbrp exhaust.

turbo failure

I know this is an old topic but i'm hoping I can help anyone else that may run across these posts. About 3 weeks after removing my stock muffler and hollowing out the cat my turbo killed over. I'm not really diesel savvy but I'd hate for this to happen to someone else who is considering a homemade exhaust mod.

04 6.0 lariat cc fx4
edge mileage max
hollowed out kitty and muffler delete
wanting many mods but funds are being sucked dry by diapers and wipes!

Stock 2005 F250 4x4 6.0 with 66,000 miles on clock. Three turbos so far.

First failed at 28,000. Second failed at 53,000. Third failed out of box. Hopefully fourth will last until the truck is sold.

Driving history. First 28,000 did not pull trailer. Truck not daily driver so sits for long periods. Maybe a month at a time. I know this is not good. Last 35,000 miles. I have pulled a small (7,500) trailer more than 30,000 miles. Miles per engine hour are over 40 so it's a mixed bag of long rides and short stop and go driving.

heater needs to wake up and smell the coffee, lots of advice here on how to deal with just about any issue the engine has. by now now the mechanics have this engine pretty well sorted out. if they don't they are just parts changers and won't be getting anywhere near mine.
