Give me about a week guys and I'll show you an AOS ventilation tank I'm working on for the EG33 PCV.

Point being....PCV system is for emission. Those that say that the vacuum created by the PCV creates power.......true and not so true. Crankcase vacuum creates power, but for the average motor not until you see levels in the 10"hg range which the PCV system cannot create in any operational level of the motor that makes any benefit. You need an external source of vacuum to provide this like a vacuum pump used an many top fuel motors.

The problem is that too much case vacuum is bad and one must be cautious in doing so.

Most will suffice with a simple catch can with case lines run to it, PCV manifold port blocked. The issue with this is oil consumption(rather oil "trappage" in the tank as I called it). Its a big problem on the EJ motors and why the AOS's options are being made(by which the Crawford one is the only one I find to truly work, and I've tested nearly all of them out there).

A true functioning AOS is the trick, and something I'm working on right now for my car as I'm smack in the middle of some manifold/fuel system work and too wanted to nix the oil issue in the butt.

Parts are on order and should be here mid week. I'll show you what I can offer as a solution for a fair price.
