1990 Honda Accord radiator fluid leak, cause unknown

So, I replaced my valve cover gasket. Easy job to do once I took it all apart and looked at it. I had to actually pry it off with a prybar and scrape some of the old gasket off(made sure I didn't leave debris in there). However, I now have an insanely slow leak of coolant where the top radiator hose connects to the engine directly below and to the left of the valve cover.

the leak is coming from where it connects to the engine, not a hose(replaced hoses and upgraded radiator in '07).

I'm just looking for a name for this part, and perhaps how serious this issue is. I'm still letting my rtv cure so I haven't started the car up yet to see if I start puffin white smoke out of my exhaust. Should I refrain from testing out my new valve cover gasket until I resolve this slight leak?

EDIT:
I have discovered this is my "Water outlet gasket". Does this indicate water pump failure, or did I perhaps crack the very old gasket by hammering and prying on the valve cover? My newer question in a nutshell is this: How do I know if anything more than a replacement gasket is the culprit?
