Maybe i should start off better? with more info. I have a 2004 6.0 Harley. I pulled into my shop to replace the silicon elbow on turbo return. Decided to clean turbo while there. Put all back together and went to start, nothing just cranks and cranks. So i thought maybe some wire chaffing or connection, something simple....yeah right, now on week two of diagnosing the issue. Started off by pulling codes, came out with 2623, so went to the IPR with buddies snap on scan tool to watch and see if the IPR was functioning. Seemed to be, came up to 85% trying to get the oil to build pressure, the icp actual said 0.0, and the ecu wanted 1450psi.... So my thought then was lpop, i removed the filter and pushed down drain valve, filter housing filled up in 5-6 seconds, and when I released the valve oil drained. Thought maybe that the plunger was sticking a bit on the regulator to lpop, took it out cleaned looked fine. So then though hp leak... Hooked fitting into ICP took off the hpop cover, pressurized and system held pressure.... dummy plugged the turbo drain back tube... no leaks... So where im at, is that i seem to be loosing oil to feed the hpop from the filter housing..... I dont get it, i understand there are two bypasses in the filter housing, but trying to figure out how it could actuall y be fixed without replacing the whole housing, any ideas would be greatly appreciated!!!

Thank you fluegy, I was actually able to resolve my problem on the 911 forum. It ended up being two things that worked together, to make difficult. Broken drain back valve assembly, and the filter housing canister!! Thank you
