I just replaced the water pump and all the orings myself so they are new. In my case, it has been leaking the same before and after my water pump replacement. In order to remove the bottom half of the Alpha I gen2 drive that I had to remove an oil ...
I am having the same issue, I am thinking it may be the Oring where the tube feeds into the lower unit, but I haven't figured it out, yet. I don't see any visible oil anywhere when I visually inspect.
