It's not your thermostat housing, is it Denny? I've chased a couple leaks on mine and it seems like that water can just seep along a crevice or groove and not be noticed before finding a place to pool up and drip. I thought my pump was leaking too, but it ended up being a real slight weep at the hose that was barely noticeable till it dripped from under the pulley.

P.S. There's always Bar's Leak
