Crankcase ventilation directly to atmosphere? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Here's the deal, My SR has a vent port from the back of the block, tying in with the "T" on the head vent, then running to a catch can. With the way the new turbo/manifold/downpipe fits in the car (ae86) I'm tight on space, and am wondering if I can leave the block ventilation port breathing on it's own to atmosphere, and run a line from the head ventilation down to my catch can, then up to my intake from there.

Long story short, getting a hose from the block vent port to the catch can is a pain, I'm feeling lazy. If it's not going to damage anything, and it's not going to puke oil I'd like to just leave it to atmosphere.
