Rb25 Pcv Size? From Sr20?

[hardsteppa]

pcv valve on my rb25det is leaking under boost, and grommet looks pretty old too. Having trouble finding info about part numbers or anything in stock at parts stores - anyone know if the s14 and 15 sr20 PCV's are interchangeable with the rb25? they look the same, and has been confirmed they use the same grommet part number so the rocker side would be same size, just want to know if the manifold hose fitting is a 10mm barb, same as the rb25

thanks

hey let me know if you find out what to replace it with mate, i split my gromet (ouch) when i tried to take my pcv out.

easy enough to get thru nissan- did myself a while back easily enough.

Just get an oem one and put it in there. Cant see the point in dicking around with it as its a point that can easily generate an annoying vacuum leak...

There is a tiny difference which I can't remember but I used my pcv valve with S15 grommet and works fine. Got it from Nissan for 15-20 from memory

Thanks, i know the grommets are the same, just trying to confirm the pcv valve is same for rb25 and sr20

thanks for that. Just heard back from a stockist the sr20 one (for s14 and s15's) is also a 10mm, so looks to be exactly the same size, and also used on a few other engines.
