KA24E PCV valve on RB20?

[RustspecS13]

I was just reading through the PCV threads and I remembered I used a KA PCV valve on my RB20. They looked externally the same, but I didn't know if they had different valves in them.

I did have oil in my charge piping the last time the car ran, which was at drift practice so I was going to setup a breather tank. But now I'm thinking maybe its because my check valve was allowing boost in the valve covers.

Any way who knows of the proper PCV check valve to use on an RB20? I'm not sure if I have my stock one laying around.

I would assume that any PCV valve would work. As long as it fits your hose.

All it is, is a 1 way ball and seat check valve.

If you blow one way it should flow freely.If you blow the other way hard it should not flow at all, if you blow lightly then it should flow a bit.

But you should hook your vacuum connection to you intake pipe. You shouldn't ever see positive pressure there.
