'06 silverado 6.0 has low oil pressure at idle/stop. Gauge goes to 8lbs, chimes go off. PSI's go up as RPM's go up. Truck is making no noise and no smoke. Changed the sending unit. Mech. Gauge shows low pressure as well. What could be cause of low pressure? Do these engines have plastic check valves?

My info shows 6 psi@1000rpms. Shows 18 psi@2000rpms. MOD shows these specs. They are probably minimum specs, so the reading could be a little higher. These databases are not always correct, but, I don't carry these specs in my head, so I have to look it up.
