EGR/Turbo cleaning question

I've got an 04 F350 6.0 w/114,000mi on it. I just bought it last week. It was a former 1 owner work truck, so I figure it's been ran pretty good.

I'm planning on cleaning the EGR valve and the Turbo. I have read plenty of write-ups on both (including the TSB from International) and feel pretty comfortable doing it. I have always done my own maintenance/repairs on my trucks but this is my first diesel.

so my question is, I've read some write ups that talk about having codes and diagnostics ran after you clean the EGR and Turbo, and some that don't even mention them. I plan on disconnecting both batteries while doing the work because of the EGR being electronically controlled, when I reconnect them won't the computer self check and recalibrate anyway because of the loss of power?

Are the computer diagnostics a must?

and can I get the turbo O-ring from the ford dealer? if not does anybody know where I can get one

You can get a kit from the dealer that will give you all of the stuff to reinstall the turbo. Its only a few bucks. and if you disconect the batterys then you should be fine with the computer. good luck man the jobs are very easy for a drive way jobs.

I never messed with cleaning the turbo. it doesnt look hard but i have no problems with it so im not fixing what isnt broke.

as far as cleaning the egr valve, you just take the 2 bolts out and pry it out of there. its going to take a little bit especially if it hasnt been removed or cleaned in a while.

disconnecting the batteries will be fine. I never go back to the dealer for any reflashes or anything like that.

I have read the write ups on EGR cleaning. Everything went well, I guess. Cleared the computer, and the code and CEL came on again two days later. Is EGR valve replacement the next step?

that or deletion. but as far as the code is concerned, if its like most EGR's, you usually have to drive 70-100 miles before the code resets. After that, I would say the EGR is shot if it still throwing a code at you.

and as far as the turbo is concerned, its very good preventive maintenance to just take it apart and clean it once in awhile since its a VGT. Often times 1 or 2 of the vanes get stuck and all you notice is a little bit of hestitation before it seizes up. There's actually a great write-up for cleaning turbos

I just saw this today, and it actually breaks it down Big Purple Dinosaur Style for you.

I drove about 400 miles after the CEL came back on. So you are saying that it should have cleared itself by then? Also, the code is 0460 which says excessive flow and/or defective fuel level sensor. The fuel sensor problem is supposed to show a flucuating fuel guage and that is not happening. In a sticky in the tech section it lists the need for a reprogram if these codes appear. Just bought the truck so how do I know if the reprogram happened? Is the reprogram mandatory like a recall or does the dealer charge for this?

Thanks for the help. I plan on a delete at some point, but paid cash for the rig, so I need to recoup first.

dealer usually charges hourly rate to do the reprogram, or flash as we call it. If you already have 400 miles, I hate to say it, but the EGR is a total loss. Luckily it sounds like its probably stuck in the closed position (if stuck at all) since you're not experiencing other problems like high coolant temps or high exhaust gas temps (or are you?)

I can weld, but that looks like some pretty serious fabbing. I would not consider myself that talented.

And no, no other problems. The truck runs pretty cool.
