Not saying it is the best way to do it, but here is my set up



One line goes through catch can to the PCV.
Other Line goes through the catch can to the head breathers
I kept the "equalizer" tube between the heads, but plugged the middle piece that used to go to the PCV I think.

I no longer have the PCV solenoid valve in the system but I still get crankcase ventilation when the turbo is spooling because I added a nipple on my intake for the AOS to draw a vacuum from because I figured some crankcase ventilation is better than none and since I'm breaking in a new motor I wanted to give the rings the best chance to seal. Crawford says you can just vent to atm if you like but like I said, some is better than none.
Yea I do not have the solenoid anymore either but wanted to see what guys thought about venting to atmosphere or if it is necessary to plumb back into the intake.

This is the other option I am thinking about with a short "intake" basically a pipe with a couple of fittings or nipples for the lines.

10 - 4. If you do it, be smarter than I was. Weld your fittings around the pipe not down it.
the reason I took that picture was to show how tight it was in there. If I did it around the pipe I would have had plenty of room.

I bought 2 new weld on fittings but my buddy who tig welds is laid off right now, and I dont have a strong desire to pay someone to weld those two little things.

I draw my Crawford AOS through my CAI so that the intake would help pull crankcase pressure from the heads. Faulty logic?

I have the pcv valve in the intake manifold plugged, and one port in my case plugged. 2.0 heads on a 257.

I'm realizin that I'm not really venting pressure anywhere...

I see the logic, your oil just recirculates back to pan

I am running a 4Ętube and air filter with pump gas map, and no air filter with meth and pump map,and same for race fuel map only a screen to avoid little rocks from getting to the turbo, oil catch can,no pcv. since you are not running maf any more you can go with bigger tube for your air filter.

Ordering a clutch this week possibly. Clutch Masters FX400 w/ the flywheel.

Also decided to make the trek to TX2K13 this year so we will be getting some of the issues ironed out this month and getting her ready to rock and roll.

Why the air filter on for pump and off for meth? Why not just pick one or the other? I know some people see 15-20 ditching the filter but why not just always keep it off or on?

That is the plan my friend!

It'll be weak **** compared to the rest of the vehicles there but I don't care, the track conditions will be the best I have ever seen and I am hoping for a fast track.

Yea I think we can get it done. I need to get the intake sorted out and then get the GM IAT sensor wired in and ditch the stock MAF sensor.

When on pump map I use car for DD and I live out on the hills, with dirt roads,dont want that dust to get in to the engine, and when I go racing there is no problem there, as far as removing the air filter and pick up a few extra ponys

Or could someone just explain why I shouldn't just vent everything to atmosphere? I know it isn't ideal but what am I really going to run into by doing it this way?

I don't think it will hurt anything it will just not have any vacuum to pull from the heads.
