Finally some one that knows where these things should be installed

Depends on the can. Some are intended to be drawm through back into the intake. Some are intended to vent to the atmosphere. The canton unit I run has an inlet from the v-cover and a breather filter at the outlet. Either way it needs to have a series of baffles inside to separate the oil from the air.

I suppose the vent to atmosphere ones are intended for turbo engines where you actually have positive air pressure blowing air out of the valve cover. Our stock PCV setups suck, literally :D

Most of the cans out there are for looks plain and simple.

If you want a functional can get something like this -> http://saikoumichi.com/SPLIT_DC3_page.htm

Yes it is pricey but if you are buying something for function make sure to spend the cash on something that works!
Read through the page he talks about the vapor issues and also using a dual system for the crankcase and the PCV setup.

Here is an install on a tC. The guy does a nice write up http://blog.scionxtc.com/blogs/archi...catch-can.aspx
Also yes, you want to plumb it like OE in a closed setup so that the vacuum pulls as it is supposed to. Checkout these one way valves as well http://blog.scionxtc.com/blogs/archi...rank-vent.aspx

Yes, I am about overkill.
