You guys kill me.
So Im gonna play devils advocate and ask retorical questions for everyones own edification.
1)Who can tell us why the crank case needs ventilation?
If you can answer this question you know why you dont need a line running from the crank case into the intake?
2) which goverment industry mandates bullshit like this and other emmisions regulations like catalytic converters and 14.7 afr closed loop fuel injection, why?
3) Did the internal combustion engines always have a pcv setup?
4) How many nascars/race cars run a pcv system?
5) what happens if I just plug the crank case and dont let it breath?
6) what happens if I unplug it and leave it open?
7) why do our current pcv systems consume oil?
Lets make this the end all be all pcv thread and post this bitch at the top along with the flowmaster threads.

the crank case has to vent becouse of airation created by the rotating assembly exspecialy in high reving engs. i've read where a vacuum in the crank case will increase hp and help with ring seal. but they also make vacuum pump just for this reason. i'm sure its a emmision bull **** reason why we have to have it go to the intake to be burn up instead of going into the air. if you plug it the eng will smoke like a mother and run like *** i've seen it my friend did it i told him to block off unused vacuum line when we installed his turbo and he did, well i didn't know that he pluged the pcv one off too so he gets out and hammers it and it takes off ok but didn't pull like we thought it should and it was smoking like no other like he just blew the motor we went back to look at everything and i notice the pcv was blocked off so after calling him a few names lol i unpluged it and it sounded like the eng took a deep breathe and we took it out again and it ran twice as good and didn't smoke a drop. thats all i can answer i don't do nascar i go striaght.

An added benefit is that by capping the vacumm lie into the intake it drives better and leaves more vacumm for the accessories which is nice with a cam that doesnt create alot of vacumm.

Where did you get that filter from? I like that idea. I am going to put the LS6 cover on when the FAST goes on, but I like this idea better.

let me ask one more question? Do you need one on both sides? or will the one work just fine?
I agree on the flowmaster thing too!

please clarify your thoughts on how the pcv system and pcm communicate
I dont see where they do

I got the white one and put some open air element oil on it. Its positive pressure so it should be blowing out all the time but who knows there could be some back pressure when decelerating rapidly.
