2.4l 4cyl, leaks coolant once in a while when i first start it up from the front of the block near a pulley, im not trying to sound like i know what im doing but, the oil is not milky, so its external, and it goes away after about 2-3 minutes of idling. I might have filled the radiator and resevior a little bit to full but the coolant doesnt come from the radiator overflow. Maybe theres to much pressure in the water pump from having to much coolant? let me know what you think thanks
 
I would bet on a waterpump. That motor is has a timing belt and if I remember right the waterpump mounting is behind the timing belt. This would cause it to run down and drip off the crank pulley.
