I would pull the oil cooler cover. Sounds like someone may have used RTV for something they shouldn't have. The screen under the cooler is probably in bad shape and full of the same crap.

Or maybe a continuing saga of after market oil cooler gaskets. I second pulling the oil cooler and checking the hpop intake screen. I had a dorman oil cooler failure, it sucks. Get a new ipr screen kit, clean the valve out and an updated hpop stainless intake screen. On top of that replace whatever gasket failed with oem. The dorman green gaskets would fail right around the coolant passage on the cover.

When I put shop air in the HPOP output pipe I get no leaks anywhere leading me to think bad pump.

Sounds like a ipr problem if the screens gone and has chunks stuck in it. Leave the pressure applied for a couple of minutes without energizing the ipr. You will hear air leak out the ipr until it is energized. Once energized it should stop. If the does the ipr needs cleaned with a new screen installed.

I would think that a 4000+ psi pump would be able to do better than 150 psi with a merely clogged/stuck IPR. The clogged screen should cause increased pressure by restricting how much oil can bleed off, and the IPR% was running at full 85%.

Any way to test the HPOP?

Ipr is command by the pcm. Just because it is commanded does not mean that's where it is. The pcm has no way of verifying actual ipr position. I think your pump is fine. Remove the ipr screen and apply air directly to the large hole under the screen. You should here just a very small hiss. Every ipr failure I have had could be fixed by cleaning and a new screen. Press in on the plunger under the screen with a small screwdriver. While holding the plunger down flush it with carb cleaner then blow air through it while still holding it open. Is what happens is a piece of debris get caught under the needle and will not let the valve close. With the valve hung open it can not build hpo like it should. The pcm goes to 85% and nothing happens.

Here is the source of the problem

The rubber bits in the IPR screen led me to tear apart everything down to the oil cooler and found the screen filled with the shredded remains of the oil cooler cover gasket. How that I happened I cannot yet guess.
