    Sounds like the shaft seal is leaking. Time to replace it again. What brand did you use? New or rebuilt?

    Eldorado or CTS ? Never seen a weep hole on a Northstar water pump capsule. I'm sitting here with a new AC Delco capsule in my hand and there's no weep hole - and if the pump was installed in the water crossover/pump housing you couldn't see one anyway.

    It's not a gm one. In fact I noticed on eBay the pump that may have been used. That one has a hole also.Prolly rebuilt crap

    I'd be scared to rebuild one of these - the whole thing is pressed together - impeller, seals, pulley. Hah !!! Better to spend the $50 for a new unit !!!

    Get this - both pumps I have on the shelf - new AC Delco units - are sticky-stamped "Made in China".
