We just purchased a used 2005 F250 4x4 long bed, 55,000 miles on it, as a certified used vehicle from Ford (still under warrenty). While driving it to the beach for the weekend, towing a small 5000lb travel trailer, the engine light went on. I took it to the dealer today and they said they had to replace the turbo housing, but not the whole turbo. What would cause this? Also the truck is leaking an small amount of transmission fluid, and they didnt get to look at that today, but when we checked the fluid when the truck was warm it was too full, would that cause the fluid to leak? Like I said we bought it used, and this is our first diesel, so I have been searching the post, but havent found any like this. I also read alot about tunes, but we dont know if the previous owner had any tune on it, he did have a 5th wheel hitch in the bed, so we know he towed something with it. Is there a way to find out if there was a tune on it? And what tuner would you suggest for us...I do plan on getting a larger trailer now that we have something that can handle it... Any input would be much appreciated, you all seem to know your stuff...

 

the best way to tow is in stock form thats my opinion. without knowing what the check engine light was for or what issues you were having besides a check enigne ligh no way to know why it needed a center section. trans leaks can be from any number of things over full being only one of them

 

so is there a way to make sure it is running stock, or is it safe to assume that when the truck went through the Ford certification process/check that it was reset to factory setting if they were different? I mean they overlooked the trans leak and didnt even fill up the window washer fluid...in my opinion it was not checked over all that well...the dealer did say that it wasn't a trade in, it was bought at auction. From the vehicle history report it was taken to the dealer every 3 months for regular service, ant it appears to be well taken care of.

 

So far as I know ford will not certifiy a superduty. I could be wrong I havent done cpo inspections in a long time.
Odds are it is in stock form 95% of the dealer maintained trucks are. Its rare for us to see a modded one.

 

I appreciate your input, and I feel that the truck is pretty stock other than a big tail pipe! I will try to talk to the diesel mechanic tomorrow and will keep this thread updated about the trans leak as soon as I know more.

 

ok heres an update, we got the truck back today and they seemed to do alot of work to it...Here is what the invoice stated:
Diagnose diesel engine light is on. check and advise CHRA, unison ring bad/ jammed. underboosting performed diesel pre checks. check engine & chassis for any external leaks, oil sweating through CAC connection, replaced blue elbow hose due to oil damage. cooler has alot of oil in it. clean out cooler w/engine repairs as per SSM with turbo concerns. check fuel quality ok, check oil level ok, check intake for restriction, performed KOEO self test PO299 in memory, clear codes, check for exhaust restriction ok. injectors passed click test, egr fails position test, intake coked (i am assuming this was supposed to be "cooked")severely. m-time to clean intake manifold & egr ports in combo with perfoming related repairs. clean out mixing chamber, install baffle kit, replaced egr valve, reprogrammed pcm, ficm & tcm to latest calibration. Fuel; pressure at 60 psi at filter, module at 60 psi, no areation or combust ion gasses present. Intermitant runs rough when warm. ICP @ low idle 550 psi, IPR open 22% ok. perf KOER self test. PO611 FICM code. reprogram PCM, FICM, TCM, to 5U7A-12A650-CVH. No power, performed boost test 8 psi, allowed 22 psi, jammed removed turbo, found cam arm worn & binding, unison ring worn, replace the CHRA, replace unison ring, replace drain tube, reassembled all, road test, boost at 25 psi, ok.

now thats what the invoice read, the service person I dealt w/ was already gone for the day, so i got no real explanation of any of it..so if anybody can explain it I would appreciate the help

as for the trans leak, they washed the undercarrage of the truck, put dye in the fluid, road tested it, brought it back and checked w/a uv light and no signs of leaks...so this issue is still pending...

 

wow, sounds like the dealer checked everything.

 

And the correct term is coked, not cooked. Coked is carbon, oil and/or fuel deposits that form in the intake manifold and egr valve.

 

we get ones that are in fact cooked too!

long of the short for the op....
remove and clean intake
replace egr valve
replace center section of trubocharger.
install new turbo drain tube
install egr baffle plate
reflash pcm.tcm,ficm
and and bunch of daig that we get paid for.

 

well thanks for the plain english...I am learning a lot from this forum. This is the first diesel we have owned, and didn't even realize it was running bad, till the engine light came on...I am just glad it's still under warrenty, I don't even want to know what this all would have cost.

 

By reading all the details of the invoice you posted, it sounds like the tech that did the work knows what he's doing by the way everything was documented. The ONLY thing that would concern me, is the P0611 code. I don't see a FICM replacement in there with the "grocery list" of items replaced. I'll assume the servicing tech did monitor the FICM PIDs during the diag process. If FICM_M goes anywhere below 45 volts under any circumstance, the PCM will flag a P0611 FICM performance code. Usually the symptom with this code is anything from a rough running engine to an outright no-start.

Regarding your transmission fluid leak. Where abouts can the leak be isolated to? The reason I ask is because for some stupid reason, there was an issue with the 5R110 Torqshift transmissions between late-build 2004 model years to early-build 2005 model years. The late-2004 model years were covered under what's called a customer satisfaction program that has long expired. But for some strange stupid reason, 2005 model years were excluded. What would typically happen, is the low-reverse clutch drum snap ring would work itself loose and "walk" out of the case causing transmission case damage, and an obvious need for replacement. Again, this issue seemed to be a pattern failure only on late-build 2004 and early-build 2005 model years. The rest of the other model years were virtually trouble free, other than the odd TFT sensor failure which is a relatively minor issue.

 

m-chan68, I will definatly call the tech tomorrow and ask him about the PO611 code and the concerns you have brought to my attention, thank you
