If you have a non heated pcv, then that makes you're life a bit easier. Else the coolant line will have to be capped off as ibd mentioned. That's what i did. The heated pcv setup has an extra port on the metal water pump line which goes in the valley. For drivers side pcv I'd recommend the lightning stock setup. For passenger side i would recommend an oil separator. Particularly the l&s one since it's proven to be the best one out there. I would not recommend any breathers as i believe that would introduce un-metered air into the engine, although im not 100% sure on that claim. Not to mention they make a mess.
