Car had the latest PCV system on it - but the grommet at the valve cover wasn't replaced, my bad - it had rotted to the point that nipple pulled out - so no PCV system! Not sure how long it was like that. So far I have about 40 miles on the car since completing the work and pressure still drops after it gets fully warm - but idiot light never comes on. Will check installation this weekend - may have too small a wire from sensor to gauge, making too high resistance?
    Oil gets thinner as it gets hotter, so after about 40 miles it is probably as hot as it is going to get. I would think that you have a worn oil pump which has excessive clearances.

    definitively not an option about wires gauges your issue will come up by your screen clogged, at my opinion the thinner of oil could be taking out old sludge from your entire inside engine and have clogged your screen, I will thought about oil brand and specs for the next oil change.
