EGR Valve Question
OK, I'm full of questions today. I guess it's time to confess, we are seriously re-evaluating if we can afford to keep our F350. The maintenance, sadly, isn't very cheap 
We've had the EGR valve go once at 45 thousand Km. What I want to know is will it go again and again at regular intervals? Has anyone had to have theirs replaced repeatedly?

Yes some have but not me.
I posted in your other thead about filters.
Check it out.
The best way to cure your EGR problem is for one day a mouse accidentally bumps it and it happens to become unplugged.
Don't sell the truck.
Inform yourself with threads this website. So searches and ask questions.
Buy filters at a cheap source.
Stop going to dealer for petty stuff that you can do yourself for way less money.

If I made add some input, though I don't have anywhere near the level of expertise on the Ford Diesel Trucks, I am fairly competent with cars.
As to the EGRs on cars, they are exceptionally durable, and when they are reported at "failing" or "going-out", in over 95% (my estimate) of the cases, it is simply that they (EGR) have become carboned-up. I've never had one fail !!
By simply taking it off, and cleaning it out, the problem (issue) is corrected. What usually happens, is that carbon bits (dusk) clogs the EGR and prevents it from fully closing, when it has been instructed to.
This procedure may well apply to those EGRs on trucks. I stress, those units on case, are very very durable....BTW, those units for cars run about $125 each. On my car (419,250 miles '95 [I'll leave the name omitted] I have a back-up unit, and when my Check Engine Light comes on, after reading the code set, I simply replace the unit, and clean out the old unit and then put it into the status of "back-up".

Well, I don't know how everyone elses PSD's behave, but when mine went the truck had no power, smoked heave and wouldn't drive. A couple hours later when the tow truck came it wouldn't even start! It gave no warning signs, just quit

Mine went out at 9K along with my EBP. Since it fell off I haven't had any problems.
Mine didn't cost anything because it was under warranty, but after 100K miles all that carbon built up in the intake and EGR is on me...(if it were connected)

Yes, IMO, carbon build up is the major malfunction for the 6.0 EGR valve issues.
By it's very nature the diesel would be more inclined to produce higher levels of carbon than most gas engines...one of the reasons the pesky little wart is such a big nuisance. And again, IMPO, ill-conceived for this engine design.
In addition, it is my understanding that it is a tough little bugger to remove and re-seat.
I have seen pictures of carboned EGR valves (at low miles I might add) and it is unbelievable how loaded up they are.
If you were to include cleaning this valve on a regular PM schedule I would recommend doing it at your designated regular oil change intervals.
But, alas, mine has been rendered non-functional (by some freak act of nature to be sure) thereby saving Ford an immeasurable amount of warranty $$$.
Thank me very much Mr. William Ford.

As far as full-size diesel pickups go Fords rate about average or even a little lower than other brands. If you can't afford the maintenance/repairs on a Ford 6.0L SD, you probably can't afford a full-size diesel truck.

It's not that I can't afford them it's that I can't afford the insane mark-up that my dealership charges on parts
I do take offenst to your comment as I've run the other models and know for a fact that I didn't have to buy 17 litres of oil for every change, which btw occurs monthly with my driving habits.

Because my CEL lights up with my EGR is disbled, my new EGR valve strategy is to pull the plug for driving around town which is 90% of my miles. I'm going to plug the EGR valve in for trips or while towing so I have an operable CEL while on the road. For $140, I might buy a spare EGR valve just in case I need one on a Sunday in some tiny out-of-the-way town..

I really don't think this maintance issue is all that bad, my previous 98 Expy cost 30.00 to change oil every 3000 at the dealer, my PSD cost 65.00 every 5000 at the dealer with every 5th change free. It almost averages out the same. Throw in a fuel filter change at 15,000 no biggie, as they got me on a fuel filter for the expy about that time also. The main diference Im running into is I am trying to run staydayne in all my fill ups, hoping that prevents EGR problems etc, thats a added expense. I don't know about the tires I have on my PSD but the stock ones that I had on the Expy didn't last very long either.

If you were going to pick up a spare, I'd install the new unit to ensure a good valve seal and then connect the electrical plug to the removed unit and just lay it on top of the engine. This would prevent the CEL but stop EGR flow.
The EGR valve only opens when the exhaust pressure is greater than the intake pressure.
