Ok, There are a few ways to do this and it seems a few of you may be mistaken although it could be me. The Pcv is for emmisions complience only. So it can be hooked up realy only two ways.
option 1; Plug the pcv on the valve cover and the manifold then run a line from the breather port to the can. If the can has a filter plug the other port if not then attach a filter to the port on the can. This way is for off road use only and is probably the most effective because oil vaper dosent enter the intake at all. The oil gets caught in the can and the blow by pressure is disapated into the atmospheir. This is also why its not emitions complient. It may grab less oil cause theres no vacume but that leaves it in the engine so its better off. It dosent matter what it grabs because it dumps to the atmospheir any way. You see a little steam coming from the filter at idle and thats the blow by pressure.
Option 2; put a filter on the breather end of the valve cover or leave it connected to the intake. then run your tank inline with the pcv. This puts the tank and engine under vacume so air enters the breather because of the permanant vacume so what ever blowby is created only relieves the crank case vacume and gets pulled into the tank. Here the vaper is sepperated and the oil gets stuck in the tank and the vaper gets reburned. So for this style an unfilterd and baffled tank will only work. A filter will just leak vacume and make the whole thing pointless.
Option 1 needs a filterd tank but the baffaling doesnt realy matter because it doesnt ever enter the motor its just a matter of how oily the filer will get.
So option one is non emmitions complient and option 2 is complient but still fills the motor with vaper. Its a personal choice and both work good if builr right. Thing is you need the right can for witch ever option for it to work correctly. I can post a pic of my install if needed. Im sorry for the spelling errors but i tried to be detailed and it was sent from a phone lol.
I hope this helped.

ok, so i've had some free time finally to play about with my car 
got it fully detailed with paint correction last week, so i'm a happy bunny!
i got thinking again about this oil catch tank, and i have decided to fix this issue by next week.
i read all your replies (twice!!) and also googled the subject of OCTs; and I now think that this is the best setup:
[/URL]
The blue pipes act exactly as OEM (PCV to manifold), just with the OCT in the middle, as its supposed to be.
The green pipe connects the breather valve to the air cleaner, just like OEM. This is the part where i'm not 100% sure ... is it better to block off the pipe in the air cleaner, and use a small filter on the breather?
