I rode with him to demonstrate the noise it made. He drove sensibly, there was no mods, all stock. Turbo replaced 20,000 miles ago, minimal use of additives. The turbo wasnt real coked, but there was a lot of rust. Egr was clean and hooked up.
Mark the position of the v-clamp(holding the exhaust side on) then mark the position of the"actuator arm" that goes thru the exhaust side from the center. Remove the clamp, separate with hammer and brass drift, pay attention to where all parts are(no springs), pull out unison ring and vanes, then start cleaning. Some easy, some like hard gasket material. Then re-assemble(there is a locator pin). Align "actuator arm" first, then locator pin.
The rust part was what I saw with mine also, for whatever reason. It wasn't really carbon--that part was very minimal--it was rust. Yes, Tim (nice name by the way) it's fairly easily performed. Maybe we should get the whole procedure posted here in the tech folder--pictures and all. It's harder getting to it than anything and it's gonna take some patience for sure, but nothing that a decently competent mechanic can't do.
Vloney...Is there any product that you have ever used to "Fog" a turbo? We use an a fog on our heli's every night to keep the corrosion levels down to a minimum. Just wondering if this might be a preventative from the beginning. It doesn't contain any solvents that would break loose any corrosion that is present, but it prevents build up. I know they use the fog on some of our apu's that are left on the platforms(oil rigs).
Pics would be nice too, for all of us unmechanically challenged.
vloney, what were the symptoms that required cleaning? Mileage and year of the truck?
It must've had sufficient mileage for warranty work.
Symptoms were---turbo bark,at slight throttle tip in, egr code(I think po409- dont quote me, cant remember) still ran well, just concerned about the bark. He described it as a steam engine huffing. It had 51000, was an early 04.

Dont know of any fog to use. Remember, this is only on the exhaust side of the turbo.
vloney: Does TSB 06-17-1 apply to all model years? The reason I ask is on the forddoctors site they say the TSB "applies only to 2005-2007 Super Duty ...... .This leaves out 2003-2004 vehicles and .... . At the end of the article they state that "all trucks with 2003 engines that have had Recall 06E17 will need to have the VGT Learn procedure performed..... . Since I have an '03 and have had 2 replaced so far, if another turbo fails I would like to know if they will replace it or clean it. Thanks in advance for any info you can give me. Techs like you are really a great help to 6.0 owners like me.
As per the wording in the tsb---yes, the 03-04 models are left out. As per hotline--anything with working parts that is crudded up that can benefit from a good cleaning, it most definately applies. If Ford can spend a couple hundred dollars as opposed to 2300 for a new turbo, what do you think they would rather do? Whether they will replace or clean your turbo, is a dealer decision. All 03 and some 04 models after the flash need the relearn procedure done. If there is a problem with vgt function for 5 run cycles, the vgt_lrn pid will go back to "no", and a relearn will have to be done again. The repair is clean or replace.
