2006 Silverado 4.8 Low Oil Pressure
I have a 2006 Silverado 4.8 L. Back in
October on the morning after the first cold
night my oil pressure indicator alarm started
going off. Every morning since it has gone
off. Gauge reflecting no oil pressure. Once
you start driving 30 seconds the alarm
stops. And the oil pressure builds up to 40
and holds the rest of the day. On a rare
occasion it has randomly went off. I have
already replaced the oil pressure sending
unit. Any thoughts?
