PCV valve hose. opens when the oil pressure in the head is high enough. Supposedly needs a vacuum line to open up, that's why it's connected to your intake, but since many people put air filters on or oil catch tanks, and still have their cars running it's not that important i guess.

Replacing it is your best and cheapest way. Breather filter is about $15, catch tank runs around $30-$40 iirc
