oil breather pipe

[nightshift]

my question is simple,

how important is the oil breather pipe that goes from the cam cover into the throttle body intake pipe , what is its function ??,mine is unplugged at the moment because i recently installed an induction kit that has no provision for it (i opted to plug the I.A.T Sensor into the single hole provided),although i am planning on drilling a hole in steel pipe of the induction kit,to put it back

Part of the PCV system, extracts air out of the crankcase via engine vacuum. If you have it off for now, it's okay. You can also disconnect the whole PCV system, and use a catch-can instead of your intake tract.

on this topic, where should you route it for a turbo setup?

run a catch can. there are a few theories on the correct way to run it.

you can disconnect it, but over time you'll have some carbon build up in your head. plus, you kill the "circuit" of the vacuum system.

theroies, yes... but what really works is the way endyn set up their can. if it doesn't have 3 ports + a drain, its a waste of money.
