    ...nope. It died, and I think I may have found the leak - although weirdly enough, it's not red (which gives me doubts). The high side line where it meets the condenser (on top) has some wet stuff dripping from it - there's some green stuff underneath (looks like mold, but I'm sure it's just oxidation or smth), looks like it's built up for a while (it was like that before too, btw). The point is that it's wet, and it's not red - in fact, I touched the wet stuff (this is after car off for 24 hours, ofc), and the spot on my finger it left was bright yellow/green.

    Have I found my leak? It doesn't seem like the actual metal fitting, because I don't see any cracks or whatnot - also, it obviously holds some pressure... maybe a bad o-ring? I'd love to be able to just swap that out, but I'd have to evacuate the entire system, so I don't want to get it wrong. Also, why is it not red?

    That fitting is near the coolant overflow. Smell the residue. Also, a leak will sometimes be oily (since there is oil in the system).
    The world breaks everyone and afterward many are strong in the broken places. But those that will not break it kills. It kills the very good and the very gentle and the very brave impartially. If you are none of these you can be sure it will kill you too but there will be no special hurry. Ernest Hemingway, A Farewell to Arms, 1929
