3/8 to 1/2 reducing coupler
1/2" self-tapping screws $unknown (I have a bunch of these laying around)
90 degree corner angle plate $1 True Value
Breather Blow-by Hose - 5/8"
PCV Hose - 3/8"
Mishimoto OCC IN/OUT lines - 1/2"
Go from the Breather to your 5/8" hose => reducing coupler => 1/2" hose => OCC IN
Go from Breather Hose => reducing coupler =>1/2" hose => OCC OUT
If you use the Mishimoto OCC, you're going to have an in and out. Engine side goes to the in and blow-by hose connects to the out. If you get in there and get confused, just remember, your motor is a huge metal thing and the hose is made of rubber.
It's a tight squeeze.There is a solid black bracket in front and just above the breather valve/hose. I screwed through my 90 degree angle bracket into that bracket with the self-tapping screws, then attached the OCC bracket to the angle bracket using 2 more self-tapper screws. It was not lining up properly, so I used the vice and turned the 90 degree angle bracket into a 50-60 degree bracket then reattached. Where it is mounted makes unscrewing the bottom to empty a PITA, you'll be better off unscrewing it from the bracket, removing the hoses, emptying and reinstalling.
I've only had this installed for about a week or so, I haven't checked to see if it has collected anything. The blowby hose was coated with oil, so my guess is that the OCC will work as advertised.

Hose #14 is the PCV hose, do not VTA, make sure this routes back to the intake manifold and use a separator if you wanted.
Hose #8 and #4 route back to the compressor inlets, passenger side in the coupler and drivers side into a fitting on the turbo. These can be VTA but is recommended to route back to the intakes. You can use a separator in each circuit to keep the oil out.
2: Shaun has installed Vent to Air (filtered) OCCs on the breathers referenced above, which works well.
PCV VALVE OCC MUST BE A SEALED CAN, VTA = No Joy.
3: DO NOT USE PVC couplers. Attached in the pictures is the first Home Depot reducing couplers I used. They are blue and I am lucky they didn't completely melt.

I am simply providing a overview of what I did. If you get in there and accidentally **** **** up, that's on you.
