The gauge checked out 5 psi low, so the numbers are really more like 10 psi idle and 35 psi @ 3000 rpm. I couldn't find an AC PF24 filter locally, so I'm installing a Bosch 3423 as soon as the engine cools off.
This leaves me for now with only one question. Assuming this filter change doesn't fix the issue, would a loose clearance want a thick oil (presumably more pressure?), or a thin one (presumably more flow?)? I would think a thicker oil would be appropriate, around 50W or something. What about using a solvent of some sort? Would that just make the problem worse?
