Look under the oil fill cap while it's doing that and see if you see oil flowing around up there.

To update this thread, I cleaned out the oil passage and repeated the test with a mechanical gauge. I dont have enough hose to read it while driving, but at a very hot idle, it still reads ~15-20PSI with Rotella T6 in it.
I guess that is OK for me as long as it is OK for the motor. Just want to make her last as long as I can
