Like in title I have a 2000 ram 2500 8.0l V10. Last week I lost oil pressure at idle and a small ticking sound started. Checked oil, it was low but good. Added 1 quart, still had tick but oil pressure showed around 40. Get home to work on it. Tick sounds like it's from #2 valves. Pull the cover, everything moves and torqued. Couldn't run it to see if oil moves well because well the top half of the motor is off. Next I drop oil pan to check the pick up tube. It was fine, cleaned it out just to make sure. Gave it a oil and filter change at this point. Ticking stopped, but oil pressure guage goes to zero at less then 1000 rpm, and below 40psi at any rpm above that. So I pulled the sensor and pump on a manual oil guage. It red 12-15 psi at idle and 40 at 2500rpm and goes up with rpm. Oil pump right? Well I find one, get it a week later. Take motor apart and well they sent me the pu for the van not truck. I clean everything on old setup. Looks new and everything moves great. Relief valve and spring as well. I blow out all the ports just in case a blockage. None. Get it all back together same issues. So take back the wrong oil pump, can't get the right one anywhere. And I get oil pressure sending unit. Same issue. Says low at idle and under 40 Psi at 2500RPM. Before I order just the pump gears for $111, want to see if any of you might have a idea. I added a photo of my gears so you can see if the look good to you or I'm a idiot and need to replace them. Sorry about the long read but it's info needed to get the best help. Thanks in advance
