Rb20set pcv valve location

Hi there where is the pcv valve located on the rb20det, cheers

It's in the side of the cam cover, just forward of the stock TB, facing the plenum, connected to the plenum by a shortish hose.

Is the pcv valve that one? Does it pop out or screw off haha probably f**ked as it is but don't wanna snap it off inside head

What you've highlighted is not the PCV, it's just a cam cover fitting.

Those are press fit on, you could use a pair of pliers to twist & pull and it will come out. Use a touch of WD40 to help you pull them out.

Also I advise putting a breather directly on your cam covers like that, please use a catch can.

Neither of those are PCV valves, as others have said those are just breathers. This is also a super bad idea to run as-is because the moment your engine breathes more than a non-trivial amount you are going to start spewing oil mist all over your engine bay. No track in my area would be ok with this setup, you would almost certainly start dripping on the tarmac. Also worth mentioning that uncapped manifold hose barbs are vacuum leaks, maybe less of a concern with a MAF delete but still not recommended. I would also run a fan shroud if you can source one, the engine fan is going to be far more effective with proper ducting to pull air through the radiator instead of just vaguely moving air around it. The PCV valve is long gone on your car as far as I can tell, reference this diagram to see the original setup where 11810 is the valve:

PCV Valve is the one on your manifold that is capped off. Be careful repurposing the oem pcv lines. The original line between exhaust side valve cover and intake has a small orifice inside it.
