PSD injector o-rings leaking
[updated:LAST EDITED ON 14-Nov-02 AT 01:43 PM (EST)]Ok, panel of experts...the general consensus is that my injector o-rings are bad, causing massive oil consumption (about a gallon every 200 miles). Ford wants to fix them (and a frayed turbo inlet hose) to the tune of $680. A Diesel place in Tucson will do the o-rings for about $380, but also suggest "sealing the IPR valve", and running diagnostics to see if that is necessary. Is a leaking IPR valve a common problem? is it related? If so, the price comes out about the same (if they replace the inlet hose, too). Ford didn't mention this IPR valve. Do I need to be concerned about it?
No, this isn't for the truck in the picture, it's for my other problem child, a '96 F-250HD PSD 4x4.

The question is, is the IPR valve leaking? If it is then it needs to be fixed. If it is not then I wouldn't go looking for trouble where none exists. And no the two problems are not related although you may either have a "check engine" light or a code in the computer for "injection control pressure" if your injector O-rings are no good, which they obviously are not, if you are using that much oil. If the IPR is not leaking, there is no reason to believe that the O-rings (on the IPR) need to be replaced. If it were my truck, I'd tell them to leave the IPR alone until it gives you trouble. If your computer has an injection control pressure code set, it will go away when they replace the injector O-rings.
These questions always arise when people don't understand how the system works (it is the old "which came first the chicken or the egg" question). Do we have an IPR code because the IPR is malfunctioning? Or, do we have an IPR code because the system can't maintain the pressure set point? In your case it is the latter.
If it ain't broke, don't fix it.

[updated:LAST EDITED ON 18-Nov-02 AT 09:04 AM (EST)]Thanks, Joe! You are absolutely right, I don't understand how the system works (yet), but thanks to you and other FTE posters, this newbie diesel owner is getting an education. I'll have them leave the IPR alone.
It goes in on Thursday, I'll let you know the results...

Well, the results were very expensive. They replaced the o-rings, and "resealed" the IPR valve, and replaced two of the injectors. OUCH! . But, then we loaded up the travel trailer and made a 1200 mile round trip for Thanksgiving with Mom...it towed like a champ, purred all the way, and burned NO oil. Not measureable, anyway. Before the fix I had decided that F.O.R.D. stood for "fill oil reservoir daily", but it appears that those days are over.

[updated:LAST EDITED ON 04-Dec-02 AT 09:36 PM (EST)]No, but I was puttin a couple hundred miles on it nearly every day, and it was using the oil that rapidly, so I had to Fill Oil Reservoir Daily. Now I just have to replace a 30 amp fuse every 50 miles...as you saw from my other post 
By the way, thanks for the response...even though chasing through a wiring diagram wasn't exactly what I wanted to hear. My step father said he had the same problem with his '94, and it was a loose wire in the glowplug circuitry. So, I'll get diggin.

The reason I asked about the need to refill your reservoir every day is because I advised against resealing the IPR valve and it occured to me that if the IPR were leaking (yours is an early Power Stroke engine), maybe it was draining the oil in the reservoir back to the crank case over night (I work on brand new engines and there is a lot I don't know about field related problems, so just as soon as I think I know everything, I get chopped off at the knees).
