Exactly, thats the setup I have with 2 pcv valves. I just gutted the stock pcv and bored it running to the lines for the system. Works with both vaccum as would a stock system and vents when under boost.

I have two catch cans (one going to each locaton) just to be safe so oil problems dont happen.

WTF

so you have 2 pcv's and your stock one is drilled out? right now i have my stock one drilled out but just a catchcan going to my pre turbo intake, which makes some suction not alot, almost none at idle, and i figure the stock system is pulling on the pcv at like 20+ psi at idle thats why i thought of this

not unless your throttle body is about 20mm or you're using a crankcase breather filter for an air filter...

Seriously, there's no vacuum left when the throttle plate is wide open in a N/A honda. I can post a video if you guys need it. Long story short, I installed the boost/vacuum gauge before the turbo setup, and now I'm broke, so the setup is very slowly coming together, lol.

Further proof of vacuum @ wot is in CROME. Look at the headings of the columns, and you'll see where WOT is.

WTF

so the pcv doesnt have suction except at idle? i thought wot is when your engine makes the most pressure in the crank case, i guess its just not a big deal or they would have a better way to suck it out or have some pump that would suc it out

pretty much i dont like the smell that comes out of my valve cover filter it comes in through the vents if there on fresh air so i think a one way valve to the manifold on the catchcan would keep it flowing the right way, at least at stops, anyone tried this? what does a stock turbo car use for the pcv system anyways?

it won't work. I've tested that like an year and a half ago .. and guess what, the valves don't seal perfect, so at the end you get pressure in the oil pan area, and you oil dip stick starts popin out
