I'm in the process of replacing a bad bearing on the water pump driveshaft on my '96 Corvette LT4. I'm referring to the bearing that is pressed onto the end of the water pump driveshaft with the outer race pressed into a hole high on the front face of the block just above the cam sprocket for the timing chain. The timing chain side of the bearing is covered by it's retention plate, but the other side is exposed to the interior of the lifter gallery. Since the original bearing went bad, I began to wonder how this thing gets lubrication during operation. I see no obvious direct path for oil to get to it. Having said this, I have two questions, 1)how is this bearing lubricated during operation and 2) what should I use to lubricate it prior to installation?
