I have a 2005 lly with 175k miles banks 6 gun, exhaust, intake, IQ and running a CAT fuel filter.
Normally my oil pressure would read 30psi at idle when warmed up and then around 60ish when driving. About a week ago it started reading just below 120psi and it only moves when I shut the truck off or every now and then it will do a little dance and bounce around between 30 and 120 for a few seconds then go back to 120. I just changed the oil and have only been using rotella 15w40 and Fram oil filter. Oil levels are on the full line.
Does this sound like a gauge problem, a oil pressure sensor problem or a legit oil pump problem?
Thanks for the help in advance
