Catch can setup

I have been searching all night and have figured most of this out. I kinda messed up and went cheap and orderd a ebay catch can. Now that we have that out in the open how should i hook it up. Can i just vent it? Really dont like the idea of pouring oil vapors back in my intake and through my turbo.
So what i was thinkin since i went cheap and im broke is can i leave the breather box open run the catch can were the pcv went into the back of the bock or whats a good way to do this. My pcv system isnt working i busted ringlands on 2 pistons and beleive thats a major cause.
So basically im in a tight spot hve this cheapo can coming i have no emissions to pass or anything how can i pull this off and vent my crankcase. Just been reading that oil vapors hurt your octain rating just dont wanna kill my motor and im really in a tight spot right now guys. I have dumped so much cash on arp studs,acl bearings,rings,cometic head gasket, a gasket set, and now pistons because i cant afford forged right now. Any info will be well apriciated.

the best way with a cheap can like that and no cash would be to hook up the can between the pcv and the intake manifold. you won’t be venting anything but you’ll at least trap all the oil before it goes back into the intake manifold.
