Mine been doing same thing for over three years now with low enough oil pressure at idle i unplugged the sending unit so i didn’t have to listen to the dam thing bing bing at me you damaged a lifter or spin a cam bearing when you was reving it up when it was cold for sure I did same thing always let your vehicle warm up on its own but don’t worry to much cause these motors are tough as nails and it will run a very long time on little and no oil pressure like I said mine done the exact same thing yours is after I revved it up to warm it up fast one cold morning that was over three years ago and I replaced every single thing you can think of with no change in pressure main bearings rod bearings pickup tube o ring times 2 pick up tube oil pump timing set oil pressure switch times 3 tried three different brands there is no filter under the switch but I like you didn’t know bought one of those too still got it cause they will sell it to you at the parts store I put a manual gage on it and it read same low oil pressure as the factory gage ended up meeting a guy who did same thing we did with same issues after and he had damaged lifter and spun can bearing
