Been a long time since I've hit y'all up for guidance, but it looks like it is time once again...and I see the place has changed big time, when I first followed one of the google links I thought it was a different place, lol.
2004 late build, out of the blue started with multiple long cranks to get started. Once started I noticed the "check gauge" light and that dash oil pressure gauge was at zero at idle, but would recover once I was off idle. Google my symptoms and pull up a number of posts here with same symptoms and all seemed to be the HPOP. A little further reading showed that there was an apparent HPOP style change toward the end of the late 2004 build (June or July) mine was built in April, ICP is on the passenger side valve cover.
Chatted with my local Powerstroke shop and he doesn't think it is the HPOP since it is a late build and feels the issue is in LPOP system. I left the truck sit for a couple days, was able to do some poking around yesterday and today. I pulled the oil filter, found it to be kind of dry...expected it to be somewhat wet but then again the truck has sat since Tuesday. Then I pulled the ICP to check tat there was oil in the rail...there was and oil flowed out of the hole when I pulled the ICP. I think that is a good sign my dummy plugs and stand pipes are OK. Then I cranked and was able to fill the filter housing, although it took a few seconds (I didn't depress the anti drain button) but the oil flowed faster than it was draining. Put everything back together and still had to crank for 3 or 4 long cranks, 30ish seconds or so before it fired up.
Today I pulled the pressure regulator to make sure it wasn't stuck. I don't believe it was as there wasn't much pressure on the cap as I was unthreading it and the slide came out easily once I stuck the magnet up in the bore. However, it appears that there is some scoring on the slide
I'm thinking I should probably put a new regulator in to ensure the scoring isn't from it sticking and the ensure the spring isn't weak. Anything else I should look at before I resign myself to pulling the turbo and popping the HPOP cover to see if the side hole is missing a pressed in ball bearing?
