What is that little ribbed box on the back of the b18 motor in a 92 integra? It has two hoses coming out of it and one goes up to the intake and then into the pcv valve?

I assume its like a catch can of some sort? Problem is i broke the hose coming from the intake and now the car is losing oil quickly between oil changes, about 2 quarts. The car only smokes a little on heavy accel. Never used to use this much oil before the part broke.

I need to know what i need to buy to fix this. I dont know how the hose is attached to the bottom side of the intake, if i know how its all put together i can probably fix it.
