I'm having almost the same problem with an '03 I'm working on, except it only acts up when it's warm, above 123 deg. Air testing the HPO system cold reveals nothing and it starts right up. My readings were about the same as yours. All the components have been replaced, just like yours. One time I managed to get the air to it before it cooled down and I could hear it leaking on both cyl. banks. But I couldn't tell the source of the leaks. It wasn't on top at the rails, but down deeper. I have the top end tore down to the basic HPO system now, so I'm going to plug in the block heater while it has air pressure on it and see if I can get it warm enough to leak. I'm sure you probably have a leak in the HPO system same as I do. Now that I can get to the ICP sensor, I'll feed the air in there - had to use the plug on the oil rail before, maybe that wasn't the best place? Have you done the air test? Sounds like that's the only way we're gonna find the leak. 2003 models are notorious for HPO breakdown. There's a boat load of o-rings in the system, and it only takes one to leak and mess up the whole shootin' match. I'm still trying to figure out if this engine has standpipes in it? I can't see any. It looks like that oil tube screws into the head. Do you know? Thanx!

It's very common to have a failure in the IPR screen after an oil cooler installation. Debris falls in and eventually travels to the IPR causing a failure. It may even be common to go through more than one screen depending on how much contamination entered the oil system. With you IPR% reading 85 it seems like it could have jammed the actuator inside the valve. See if you can take a look at the screen first. If you find that that there are is a tear take a small screw and push the valve inside the IPR while spraying WD40 into the holes on the sides to clear it of contamination.
