I am having the same problem, water pump was replaced last summer(like six months ago) and luckily I bought the pump with a lifetime warranty, meaning.... I can get a new one once. There is a little weep hole on the bottom of the pump as well as the weep port behind the pulley on the top of the pump, to which you can see the shaft of the water pump. On the bottom there is another weep hole that has a ball bearing set into it. It is leaking from that weep hole with the ball bearing in it. I know my water pump is working fine otherwise so, do I change the pump out once again or throw silver stop leak in it (the silver colored powdery looking) and see if it stops leaking? Knowing I have a lifetime warranty and the pump is working fine otherwise, I will try the stop leak first.
