I replaced my water pump last week with a new OE unit. It leaked (dripped, out the weep hole) immediately upon starting, perhaps 20 drops, then slowed, eventually stopped when the engine warmed up. Repeated this process several times. Then it appeared to finally stop leaking altogether. Took it for a couple rides, no leakage. Sitting in the garage this week, dripping again, not running, ever so slowly..I'm sure I have all o-rings in place properly, I've done this job twice before successfully. It would have to be the shaft seal(s) on the water pump leaking (from old age, dried up?) , correct? Or could it be the o-ring that surrounds the water pump body, got pinched during install? There's no cross contamination of water/oil, just this annoying (frustrating) slow drip from the weep hole...anyone have this problem with new water pump replacement? Should I have lubed (rejuvenated) the shaft seal(s) with a shot of WD40 before install?
