you need to check it with a gauge from an oil port, not your instrument panel, and make sure you have pressure before you lose your engine.

I take from reading this your uim/lim failed? How long did the antifreeze sit in the oil pan? Sounds like the main bearings are going bad. Most likely do the the intake failure.

Do like ru1313 said and check the pressure with a mechanical gauge and verify the pressure when hot. How low does the gauge read when hot? Replacing your t-stat to a 160deg and changing to a heaver weight oil may help keep your oil pressure up a little higher. It's not a fix but it may buy you some more time out of it.
