PVC and venting question
I’ve got a couple questions on pvc and venting.
im currently running a NA ls2 402.
i have a catch can running from my valley to the can then out and back to the intake with the pvc valve on that side. I also have a line running from the clean side valve cover to the section in between the MAF and TB. I had a breather oil cap and a line running on the dirty side valve cover to a separate breather but it looks like some stay it’s fine and some say no fresh unmetered air. Any thoughts? I can’t believe I can’t wrap my head around something that should be so simple.
I just want to know I’m not going to create extra pressure.
thx Rich

Any unmetered air will change the AFR. Simple as that.
