Air leak from refrigerant port causing leak

I was inspecting my AC this morning. I found water and some outside rust on my unit. First I thought that water might have leaked from outside and made its way through the insulation. Upon further inspection this evening, I find that both the refrigerant ports (in and out) was leaking good amount of air that was hitting the cold pipe and causing condensation. So the question that I have today is

1. Is this normal?
2. Can I plug the extra space around the pipe with something? If yes then what?
3. If #2 (plug the extra space around the pipe), is it not going to condense somewhere else?

Attached in the picture. The inlet pipe is insulated above the outlet pipe but the insulation is catching all the air blowing out and creating condensation. I added that 3M tape so it wont rust even more ...

The ports need to be sealed. Mediocre installers do sloppy work and this is typical sloppy work. Merely adding the aluminum tape in a manner that stops the air flow should be sufficient.
