Thanks for input. I updated the pic as well. It appears the coolant droplets form from the center of the crankshaft pulley. But again I wonder if its just coming from the water pump above.
The thermostat & water pump look pretty dry and clean from all visible angles, without taking everything apart. The car has 190k and I had the thermostat and water pump replaced around 80k. I wonder if its time to get in there and do it again. I just wish I could see the source of the leak.
