I had another turbo replaced earlier this year. The "faulty" unit only had 12K miles on it. It did have a stainless unison ring. At least it was nonmagnetic. The vanes still stuck from the truck sitting for several weeks. The cast iron turbine housing rusts under the vanes and at the inside diameter of the unison ring locking the vanes. So the stainless is not the cure.

sounds to me like the only real fix would be to get away from the VGT and get back to the good ol' fashion fixed turbos. i am following this really closely cause i am gonna be going on deployment for 7 months next year. would it be possible to treat the inside of the turbo before it goes into storage to help prevent rusting?

Mine was replaced at 15,000. It lasted approx. 19,000 miles. Last week, at 35,000, it was cleaned (this is Fords protocal for stuck turbos) they used carb & brake cleaner to clean it. Yesterday it failed again. Today I took it to a different ford dealer.
Ford said the 6.4 L has an enrichment circuit that injects additional diesel into the intake to clear out carbon and prevent build up. But, it used a lot of additional fuel.

My dad gets some fogging oil that he sprays in the intake of his snowmobile before storing it for the summer, probably be good for a turbo as well.

Deployment mxer0022
I just got back from a 15mth deployment my wife only put 900 miles on truck. It took me 3 tanks to clear the injectors plus I purchased some hotshots which has really helped clean up engine. (i would even think about buying some of that and run it for awhile before u leave) I would seriously think of letting someone drive it or idle it a little every week. I have seen to many soldiers who stored thier vehicles for deployment to spend thousands of dollars on gaskets and other stuff because it sat. Since your deployment is only 7mths (u know how that goes) mothballing it would be ok I guess. These trucks just cost to much and are meant to be run as a desiel should be. Good luck on your tour Ill be going out the door again in the near future also.

Problem is the variable vanes are on the exhaust side of the turbo. So fogging the intake side isn't going to help much. Not real sure how the lubricate the exhaust side short of removing the downpipe and fogging from that end.
