although this thread says for l99 and ls3, it applies for the v6 as well.

I replaced the NCV side of my PCV system with a breather on my LT1. Haven't had any problems, and its one less hose running across the top of an already cluttered engine.

i'm so confused about all this pcv/ncv stuff. i'm hoping once i get it in and read the instructions, i'll know what i'm doing. lol

In my experience, there isn't much of a purpose other than what Xanthos mentioned. It's illegal because it releases unrestricted engine vapors into the air. It's bad for baby ducks and flowers n stuff.

Haha. Maybe this will clear it up:

The crankcase ventilation system is designed to pull filtered air through the crankcase and into the combustion chambers, where excess gases can be burned in combustion. The goal of a breather/catch can setup is to keep this system in place, but keep oil out of the combustion chambers. A catch can alone cannot accomplish this, because it only filters oil out of the positive side of the system. This catches most of the oil, because its the normal direction of flow for the system. However, during zero vacuum (such as at WOT) the system can sometimes reverse flow (meaning air flows from PCV to NCV). Because of that, a catch can wouldn't help anymore. Replacing the negative side with a breather makes it to where air flowing in reverse does not enter the intake air, so no oil can enter combustion that way. Its not emissions legal, though, because any crankcase gases are simply expelled into the atmosphere.

I think the only way to be emissions legal on it would be to have two catch cans, one for each side of the system.

P.S. - Plus, it looks cool.

actually, the RX breather has an integrated one way check valve.

One way meaning that it allows unfiltered air OUT, but not dirt from the environment in. That's why it's illegal, those are engine vapors that haven't treated by your cats. It kills manatees and seagulls n stuff.

I'm ok with that. I'm only worried about hurting my Camaro
