take a real close look at the waterpump.... Sometimes they dont leak very much. I have been through a few waterpumps.

Take a look at your thermostat housing. I have a leak there from the aluminum warping. Also look at the down pipes from the housing where they go into the block.

It's probably coming from the weep-hole on the bottom of the water pump housing. Time for a new one. They aren't too bad.
