Possible internal leak??...suddenly I see major dollar signs flash before my eyes. I'm starting to seriously consider scraping the engine and just having a brand new one installed. With what this has cost me so far..and what its surely gonna cost this time, I could have just about bought one. If the problem isn't fixed this time, I think I'll just park it til I can somehow afford a new engine...a COMPLETE, ready-to-drop-in, engine. At any rate, they're "supposed" to do the deadhead pressure test today, if they didn't do it yesterday. I stopped by and the "tech" (and I use the term loosely) was in the process of replacing the HP oil line O-rings. The areas around them were pretty dry and free of oil, but I put it on my list anyway. If I recall the list..1.Check the electrical wires and connectors all the way to the IPR, 2. Do a deadhead pressure test on the HPOP.(I was/am assuming that this would not only show a leak, but on which side it was leaking??) 3. Replace the HP oil line O-Rings as these, according to this site, are prone to leak after a time. 4. Do a cylinder "contribution" test..again assuming that this would reveal any bad injectors(again assuming this has more to do with fuel delivery than oil pressure to the injector. Which brings me to this...the fuel pump is basically new, however, and just tossing this out here, the fuel pressure regulator, if there IS one, wasn't replaced...could a bad regulator be a cause of my headaches?? )5. Replace any bad injectors found..(Duh). 6. Re O-Ring ALL injectors..(on the premise that if 1 or 2 injectors are leaking, the rest are probably not far behind) 7. remove the top of the HPOP resovoir(sp) (it appears to come off), drain, flush and clean it out, filling it with fresh oil. (might be especially important since I don't have a clue as to the internal condition, or actual mileage, of the engine that was put in it..as far as I know, the resovour could have 2" of sludge in it) I'm trying to gain as much insight and suggestions as to what to have them check since it seems they won't check it unless I specifically tell them to. So if ANYONE in the know about such things can recommend anything I should add, PLEASE let me know ASAP. Personally, If I had more than a basic knowledge of mechanics,(and any knowledge of Ford Diesels) basic tools and a dry, warm place to work on it, I'd do myself a favor and do all this myself..save myself tons of money and get an education at the same time.
OOPS...by the way Scott, you mentioned "deadhead the pump", are you referring to the HPOP or the fuel Pump? I ask this because after having the fuel pump replaced, the SES light came on again and it lost ALL power 149 miles later (FYI...a shop in Winston-Salem replaced the pump and the IPR)
