...you start to see some evidence of moisture around the weep hole? Not a drip (yet) but I'm looking at the bottom of the w/p and there definitely is a small area around the weep hole that looks like it has been wet. Nothing dripping, pooling on the ground or puddle on the drive belt (underneath). But I guess this is an indication that the pump is going? Is it recommended to change or is this something that is the norm and can hold off on doing for now? It's on a bone stock 96 BBB with 123k on the odo. This is the second w/p (AC Delco brand).
