Long story short but had OEM motor replaced with Power Torque 4.0 from O'Reilly. Shows oil pressure around 10 psi at idle when warm (195-210). Oil sender replaced twice, temp sender replaced, crank, cam, throttle position senders all replaced. No knocking or weird noises. Checked and cleaned all grounds. AUX fan not coming on when desired, after troubleshooting suspect PCM. New radiator and Mech fan shroud.
