Default Element Catch Can Install on my Built Motor

Hello all.
I have a Cusco catch can that doesn't really catch much at all.
I've decided to go with the Element Catch can to help alleviate my blow by woes.
Phil has patiently told me how to install the can two or three times now and I just haven't gotten around to it. Well I'm going to VIR this weekend and would like to have it in for the track.
I have the can mounted in the cruise control location, right beneath my strut bar. I don't have any lines hooked up.
Here are the applicable parts of my setup for a discussion:
V8 Spec C heads that have twin breather ports on each valve cover.
EJ257 case
02 WRX intake manifold.

(1) If I have it right, Phil suggests that the two forward (driver and passenger)valve cover breathers are teed to the -10AN on the can.
(2) Then the crankcase breather, which (to my understanding) is the breather hose coming off the block about half way between the center line of the block and the passenger valve cover, is run to the -12AN on the can. Do I need to tee this in with any other line?
(3) Then the two rearward valve cover breathers are connected together and teed to the breather right in the dead center of the block underneath the throttle body. These hoses aren't going to the can in any way right?

Please provide me any tips you can think of.
Thanks,
Eric

These pics weren't taken specifically for this, but they should help the discussion for now:

That all sounds right. Do what Phil says.

And regarding #3, that's how it is from the factory. Probably to equalize pressure between the heads and crankcase, as others have mentioned.

Another couple of points.
The rearward valve cover ports are capped off along with the breather that sits atop the block right underneath the throttle body.
The hose that goes from the Cusco can to the crankcase breather will be eliminated. That goes to a question, is that actually running to the crankcase breather?
Thanks,
Eric

Cool. That makes sense to me.

That spot also may be a little low for the for the element competition can. I placed mine where the wiper fluid bottle used to be. I will post pictures when I get home from work.

Interesting point. I actually thought about mounting it by the washer bottle, but I wanted to retain that reservoir. I was able to mount the top of the Element can almost flush with my strut tower bar. I think it should work.

I like pictures

If you have a close up of your -12AN routing that would be appreciated.
Thanks,
Eric

No problem it will be around 8 or so. I get home pretty late.

Yes you have it correct. Here is a little better picture to get you started.



Definitely get it on for the track day as it will really cut back on your oil loss/consumption. I can also look over what you did at VIR.

Thanks,
Phil

For the Element Competition Catch Can in your application:

Block off the PCV fitting going into the throttle body.

The passenger side crankcase vent will go directly to the -12 fitting on the Element Catch Can

The center crankcase breather will be connected to the two rear valve cover breathers. These two ports on the valve covers are baffled from the factory to help separate the oil as our can will do for the passenger side crankcase vent.

Thanks,
Phil
