Asked by mcorbettsr Aug 07, 2016 at 08:54 PM about the 2003 Dodge RAM 1500 Laramie Quad Cab 4WD

Question type: Maintenance & Repair

I am working on an 03 ram 1500 5.7 hemi. Same as everybody else it has loss of oil pressure at idle. I have replaced oil pump, oil pressure sending unit twice, used a mopar brand 090 oil filter, after doing oil pump pressure was fine until engine warmed up. Then dropped pressure again. The very first time it happened was out of the blue dropped to 0 while driving engine shut down coasted to side and called tow truck. If you bump idle to 1000 rpm oil pressure guage reads normal at about 850 it drops to 0 again. I have same problem using 10w30 or 5w20. Any ideas?

Update 8-8-16 Hooked up mechanical gauge, it in fact has less than 3-5 psi at idle and 20-25 psi at rev limit in park (around 3800 rpm). No knocking or ticking makes me think it is not bearings, is there anything in the valve timing or possibly a solenoid for cyl cut out that may be stuck open?
