Want to clarify PCV plumbing...

[jsteele22]

Hi,

I bought an EG33 from a wrecker and I'm getting ready to re-assemble it. It came with intake manifold and throttle body, but nothing further upstream. And of course my notes from way back when I disassembled it are inadequate. I'm trying to figure out how to hook up the PCV system and have a few questions.

1) the hoses from the cam cover breathers - can they simply be plumbed into the air intake somewhere before the throttle body ? (I'm not using the stock intake, gonna fab something up.)

2) The only port I see in/out of the crankcase is the roughly 1/2" one at the passenger side rear, connecting into the oil/air separator. This makes sense for an output, but I don't see a seperate port where fresh air would be input into the case. Is there a seperate fresh air input port somewhere I'm missing, or does one port do both ?

3) In the parts diagram at subaruparts.com, there is a part (#11821) called "Connector-purge control valve". I can't find this part in my pile, and I don't quite get what it does : is it simply a connector, or is also a valve ?

4) Is this part the answer to question (2) ? Does it take fresh air from one hose and let it flow into the crankcase, and then direct dirty air coming out of the crankcase through the other hose into the PCV valve ? It looks as if it fits onto the port at the passenger side rear of the crankcase, but it's kinda hard to tell from the drawing.

Thanks for any help you can provide,

Jeff
