Im trying to figure out how to configure the pcv and catch can system on a d16z6. Ive searched and searched only to find people arguing about different systems.

So... from what i understand. The catch can (WITH BREATHER) goes inbetween the valve cover and pre-turbo intake pipe? Is this correct?

What i dont understand is the PCV valve bit.
Ive added a pic to help explain. Is the PCV valve number 2? that plastic thing?
so does number 1 and number 2 have to be capped? or can i use number 1 as a vacuum sorce for BOV? or what? please explain. Anyone?



Also heard PCV valve needs to be pulled out or something, then what?

 

Yes 2 is the PCV I ran a hose from the PCV to a catch can and the the catch can to the intake on my turbo...it seems to work fairly well...

then I used 1 as a vac source for my BOV and Wastegate, ran a hose off of 1 to a T and the split it to them....


HTH

 

thanks for clearing that up man, I was wondering the same thing

 

I've got a question.... what do you do with the other VC vent opening on the passenger side of the VC?

 

Hook it to the catchcan or suction pump too. The #2 piece comes from the charcoal canister in the bottom of the block so it's pulling gases from the block. Instead of pulling all of your gases from there (like pulling the VC gases down through the oil channels) it's best to vent both the VC and the back of the block. I just have a breather filter on my VC with my #1 thing connected to the catchcan. This spring I'll figure out a way to go straight from the block to the can without going through the charcoal canister. My catch can right now is a Gatorade bottle with a breather filter attached to the cap (bad idea, the orange cap plastic has been melting due to the gas and oil) so I need to fix that ---- too... bleh.

 

Okay cheers guys, we are almost there. But does the PCV valve have to be open? Hollowed out?

So i need to run 3 pipes to the catch can? One from PCV? one from valve cover and the other going to the pre turbo intake pipe?

Or 2 pipes, and just use a breather for the valve cover?

 

You mean the same way your mom sucks on my *****? Or is that another one of those FREQUENTLY ANSWERED QUESTIONS?
