The moisture is mixed in the oil with hot gas that comes out of breather tubes. Supposed to be fed back into intake to be burned in the engine. Rain not the source of the moisture. That moisture is just a byproduct of the combustion process.

Some people incorporate a bypass, so this goop is either discharged outside the AC housing or captured in a catch-can. Many posts on this, several with pics.

I'm going to rig a catch can inside the AC.

Is that a good idea? That empty space is an important part of the breathing system; wouldn't taking up that space be effectively the same as having a more restrictive air cleaner?

I doubt that an internal-to-AC-housing catch can would restrict airflow to engine in any measurable way.
Ditto for diverting that oily snot out of the AC housing. Thatís probably best solution for engine and worst for EPA.
Either keeps the oily snot from getting into engine.

Attached pic is one example of many found in other threads in this forum

Come on guys, the motor was sucking it's self off and it blew a big one. Put the cover back on and don't say anything.. If you want to clean it up, go ahead.
