My work truck, a 99 Chevrolet (with a 5.3 and auto) has trouble keeping up the oil pressure first thing in the morning.
I think the issue started since it is colder in the mornings. For the most part the pressure is OK, it has the most trouble at idle. After the truck is driven for 5 minutes or so, the oil pressure all returns to normal, and everything is fine until the next morning.
Its not a huge issue, just have to keep the RPMs up at stoplights to keep the oil pressure from dropping to zero until it warms up, but if there might be an easy fix I'm all for it.
Any ideas? It might have more to do with old age (160,000 miles) and abuse more than anything.
