Oil pressure… check

For the past two years, the oil pressure gauge in Big Blue has been slowly dropping. I’ve been watching it with concern and reading up on probable causes. A few days ago, on our most recent drive, the gauge barely read any pressure at all and the big red warning light was not just blinking, but full blast. After a few phone calls, I took the advice of a nearby garage owner (also happened to be a Moose) and installed a new mechanical oil pressure gauge… and look what it says! The problem is the simple $13 oil pressure sending unit (electronic device, as usual) which is already being shipped.
