A/C Suction Line Sweating?

My drain tube actually touches one of the header tubes. When the engine is running, I will sometimes see a puff of smoke from that side of the engine when I have the hood open. When I went looking for the source I saw what was happening.

That’s exactly what I wanted to avoid, so I did something about it before it happened.
I saw somewhere the guy put a plastic 90 on the back of the unit and ran the drain farther over.
Unfortunately I already drilled the drain hole before that.
It works fine the way it is now.
