your water pump is leaking and the coolant is just running along the oil pan and gasket area......look very carefully behind the crank pulley and you will probably see green coming out of the little hole on the bottom of the timing belt cover.

 

Also according to honda it's ok for the area under the water pump to drip a "little" because it's normal, there's a little bleed screw on the righthand side of the water pump which causes a little bit of coolant to drip from that area and on to the oil pan. If that's not the case the water pump gasket is probably going bad. When was the last time you replaced the water pump?

 

i put the motor in about 2 months ago , the guy that own it before said he changed it 10k before i got it.. but i did change the thermostat and refilled the rad to the max, i havent drove the car yet just noticed while fixing and idle problem ive had, ill have to get it checked out soon
