2004 6.0 255k miles new dieselsite hpop pump, oil cooler, nipple cup orings, new top injector orings on the front 2 on both sides, new standpipes and dummy plugs. Ran fantastic for about 1000 miles plowed 5 hours straight no problems.
Parked the truck after plowing, sat for 3-4 days. no start now. ipr 86%, icp 350, cpv .5 ish. icp and icpv have steadily gone down from that each time I try to start it with the last time the icp was 100. will not start with the icp unplugged. did an air test, oil mist out of the oil fill tube. using a funnel to listen, clear air leak. faint air sound from the oil filter housing and ccv tube. ipr had some aluminum flakes on the screen but not torn.
ticks me off that it ran great until I shut it off and now seems like another oring failed. will delve deeper tomorrow.

Reason: mistake stock output hpop not adrenaline
pulled the valve cover and put air to it and closed the ipr. no change in the sound (ipr opened or closed) with tons of air blowing thru . pulled the stand pipe and put a dummy plug in no air leak at all. pulled the ipr connected 12 volts to it and when it would click,it was sometimes strong some weak. grabbed the old one and tested it, same thing.
leaning towards the ipr valve. going to see if I can borrow a known good one.
