Check the seals..easy to do. I believe if the weep hole is leaking it is the mech seal..other may know for sure.

You might try tightening the backwards thread impeller nut, I know it sounds like I'm nuts. But on dyno test day 2 Dales Zilla was leaking, but not after he tightened it! And the testing resumed!

drain fluid, take off reverse thread bolt that holds on impeller, check to make sure rubber coated washer is in good shape.
clean area and put some rtv on bolt and shaft where bolt goes in at. put back together and let dry up some then tighten.
laek should stop. but if shaft was not changed it might have a wear groove this may be problem if rtv does not stop leak.

i have also had this problem, i stuck another washer in the stack of the impeller bolt. it put more pressure against the seal and stopped leaking.

I'm so worried about taking my water pump off the clutch case cover because it wasn't leaking and I'm afraid after I remove it to polish it and the case cover I will have a leak problem.
