Argo,

Could it possibly be a hose that the clamp has loosened a little on. Also check around the thermostat housing. I had a leak on my stroker that I hunted for a year and it would just have one drop on the right side of the bottom of the block. After changing thermostat housings and a hundred other things I found out that one of my intake bolts had backed off 2 pounds from the torque settings. I retorqued them and have never had a drop leak since. Now I just check all the torque settings on a regular basis and it is amazing at how the aluminum intake to aluminum heads can start to loosen some. Wish I knew more to help you but I am sure some of the other guys will chime in with somegood ideas.
