RB30 PCV valve thread

[XStatic64]

Hey all,

Have put a catch can on my rb30, it is vented (track car, so doesnt matter).

I have removed the PCV valve from the plenum but trying to track down the thread size of this valve, I am after a barbed fitting to screw into it's place (either 6mm, 3mm or 1/4 barb) for my boost gauge.

Other then that there is a barb on the back of the plenum which connects to a metal line for the automatic transmission, anyone know the diameter of this? looks to be 6-8mm, so would need a T piece 6mm to 6mm to 3mm, anyone know if such a beast exists?

if its turbo leave the PCV valve or u will pressurize your crankcase and cause all dramas as it is a 1 way valve and closes with pressure in your plenum.. as for your other question, get a Vernier or take it to pirtek/enzed and get them to measure it. or take your pcv valve in and get them to match the thread size/pitch to it as a barb.

Why do i need to leave the pcv valve if running both breathers to a catch can? not sure i get it

Catch can does have a breather filter on it, venting to atmosphere...
