And here are MODADDICTS thoughts, on why we need an air/oil separator, incase you don't want to have to read the whole thread.
Here is S197 PCV 101:
Follow this closed loop PCV system in your mind. Our cars draw air IN to the passenger side cam cover. This air comes from the intake tube AFTER it has passed through the MAF sensor so it has been cleaned by the air filter and metered by the MAF meter. This air circulates through the motor and is sucked OUT of the drivers side cam cover and into the the intake manifold BEHIND the throttle body. This suction draws oil vapor with it from the crankcase and this oil will contaminate the Air/Fuel mixture, create burnt oil deposits on your pistons and valves, and put a nasty coating on your supercharger intercooler if you have one. Not to mention shortening the life of your $90.00 spark plugs and gunking up your throttle body not to mention other more sinister long term possibilities.
So, you put an Air/Oil separator in the line that runs from the Drivers side cam cover to the intake manifold. Spend the money and do it correctly! Don't skimp and get the thimble sized glass one (like the junk steeda one posted in the thread) because it will fill too quickly and become a maintenance issue. Don't try to save money and get a "catch can" (like the SHM 2V one ham asked about in this thread) because it is cheaper. It will require modification to work properly. Get a good Air/Oil separator and plumb it properly.
Now you don't have to use this parts list and some complete kits like the stefs are good units. But if you want the balls best, here's the recipe...

Trust me, a catch can with good SS lines and good fittings is the the way to go on our cars. Don't skimp on the lines and fittings, that's the most important!
Even if you're not seeing a lot in your TB, believe me, if you broke down your blower - you'd find tons under the manifold. Everyone FI should have a good catch can set-up IMO. It's relatively cheap and easy and just plain smart.
I would and I don't even have it. The Moroso can is the exact same thing and it stops 100% of the oil, but it only comes with -12AN fittings.
Whatever you do don't pay $44 for the summit racing -12 AN blue twist tight hose, it will collapse under vacuum.

I've seen it (oil) in the heads too.. A modded KB with 10,000 miles looked terrible manifold down. You can't see it happening but it's there...

That's for a 2V...

this would be mounted to the drivers side PCV metal tube, with a small piece of hose, acting as a barrel adapter.....
I think that would work fine. The rubber oring where it threads together would be my only concern, but if it's made well, and it looks to be, then it shouldn't be a problem.

I like the stefs and it does the job okay but regardless if you use the stefs or morosso can, the real important factor is the lines and fittings. The can isn't much good if the lines are trapping at all.

That is basically what i have now.....but I am not boosted, i think I would upgrade for sure as that one is barely sufficient for my setup as it is now.

You can order the Stefs with any fittings you want, that way you won't need the expensive reducers. Not to mention adding in a reducer is going to make for one long fitting.

If you wanted to vent to atmosphere with k&n pvc filters on bothsides would there be any issues besides cleaning filters and maybe your valve covers from time to time .

Good point. I was just giving the the list I used as an example.

Personally, I would not do that on these cars and ESPECIALLY on a car like yours that is planning on a lot of track use...
