Warmed up oil pressure would idle at like 20, 25 lbs, up to 40-60 lbs. when rpms are up. If you think you have a oil pressure issue, first take out the oil pressure sending unit. There is a screen under the oil sending unit that needs to come out and be cleaned or replaced. Oil pressure sending unit would be out anyway, so you might as well replace it also.
So I changed my oil pressure sensor and took the screen out and I am still getting low oil pressure when it idling but goes to about 30 when I'm driving any solutions on what's wrong
change the oring on the oil pump pickup tube. They suck air and when the oil is cold it cant pull it up the tube. It's kinda like taking a drink through a broken straw. I went from 0psi at idle before changing it to 50-60 psi cold idle now. it is amazing what a difference it made. we decided not to change the oil pump and pulled the front axle, crossmember and oil pan and changed it in about 4 hours.
