'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?
have the same problem?
