What would cause a 1988 Chevy Silverado 1500 to lose oil pressure?

The most likely answer is the oil pressure control switch (aka oil pressure sending unit). costs around 4 dollars and 5 minutes to replace. It's right behind the distributor cap.

Bad bearings , a whole in the block , or a bad sending unit . Which one sounds most likely ?
