c-mac Posted February 9, 2018 Share Posted February 9, 2018 (edited) I have a truck running under 20psi oil pressure at idle hot. I changed out the pressure sensor and the pressure came up to 26psi at idle but I’m not sure if the oil was as hot. It will max out around 78 at wide open throttle, before and after pressure sensor replacement. 5500 hrs on engine.

j_martell Posted February 9, 2018 Share Posted February 9, 2018 I don't have the numbers in front of me, but 26# at hot idle sounds about right.... Maybe a bit low, but.......

GoldDog44 Posted February 10, 2018 Share Posted February 10, 2018 26 psi at idle sounds normal here as well. I never do wide open throttle but pulling at 1400 rpm is between 45-55 psi.
