Bearing wear test:
I should run a simple oil pressure test, and if at idle I get lower than 10 psi then....maybe I’m screwed..?
What is the commonly accepted min oil pressure figure at an idle of, say, 1,000 rpm..?

That is somewhat specific to the engine. Theoretically if you have any oil pressure, it will hold together for awhile. There should be a “normal” spec on the interwebs that will give you what a healthy engine will run. How far you get out of that defines what shape the bearings are.
When it starves for oil, certain parts starve before others and more damage will occur there. Rod bearings with a lot of slack increase the chance it will spin or fail sending the rod through the side of the block.
If you end up having to do buy an engine, try CL or car-part.com.
Good luck.
4.3 psi at idle. 36 psi at 300rpm. minimums.
So how did it turn out? This is what I did to my engine. Like I said, not for amateurs. http://www.tegger.com/hondafaq/sludge/cleaning_sludge.html
