6.0 diesel: Turbine carbon issue ??

[AndrewST]

Thanks for the guide great data.

Allen at SMB West told me that there is a stainless steel version of the turbo rebuild kit available which prevents the corrosion issue for occurring. Sorry I don't have any other details but you could call them.

That would be the way to go!

Cool. Very informative. Looks like removing the turbo is the hard part. Gonna hook up my scan tool and see what the duty cycle is--knock wood.

Now to understand what I'm seeing, Basically I'm 75 at idle, 55 at cruising and down to 40 on a power hill. I assume a sticky turbo will have a certain reduced range or not vary much.

Also, sticking vans can be caused by rust, which is caused by an EGR cooler leak. One of my customers was towed in after his intercooler ruptured (turbo stuck and over-pressurized). Customer had not noticed any other EGR cooler symptoms, like white smoke. But the rust was there, as was some sludge on the EGR and in the intake, indicating moisture from an EGR cooler leak. A leak like this one is often minor, and may only be intermittent as the EGR cooler expands. Bell Turbos ays 100% of the turbos they have rebuilt due to rust had an EGR cooler leak. Sluggish throttle response is another symptom of sticking turbo vans. FYI the sticking must be really severe to trigger the check engine light. However even minor sticking will store a retrievable code (must be done with a shop computer... They won't show up with basic scan-tool). __________________ 2000 E450 dually V10 wagon

Here is the update as of Thursday 10.00h (Pacific ST): The service department rep. called this morning and said it looks like they 'might' be able to make this repair under the Ford warranty. I assume that means either something was broken, they will make it appear as broken, or they do not want to charge me for the turbo cleaning (because I did complain about that). I agree about the carbon build up; how can that happen if it is from infrequent use? The stainless turbine sounds like the way to go, with regards to rust, but I assume that would take the turbo out of Ford's warranty. In any case, I am supposed to pick up the van around 14.30h later today, and at that time I should have more intel on what the issue(s) were, and how they were addressed. I will report back later. On topic: The van is just over 2 years old, and the registration is due (California reg.). The DMV requested that the van get smogged, before they bestow a new reg. Isn't that a pretty short time to receive a smog check request for a diesel? What could happen to an almost new, stock diesel within 2 years that would prompt a smog check (engine mods, exhaust changes, etc. aside, as I have none). pd __________________ parisdakar (bryon) 2010 Ford EB E350 4x4 6.0L with SMB Penthouse
