PCV Valve - PN or replacement?

[mello88]

My RB20 PCV valve seems to leak a little when pressurized beyond 5psi. I would like to replace it with a new one that seals 100% (if this is even possible). However I can't seem to find the part number or a suitable replacement anywhere. Anyone have a PN or some suggestions?

I picked up a PCV valve for another Nissan motor... It has a check valve, it threads in alright, but leaks horribly (even worse than my stocker) under boost. I can't remember if it was for the VG30DETT or not, it was just some non-oem autozone trash.

A possible solution I thought of is to remove the PCV valve and block the hole with a bolt/plug then run the PCV lines to a catch can then to the inlet pipe post-maf/pre-turbo. This should accomplish crankcase ventilation, although it'll have a lot less vac than it would have behind the TB.

Thanks in advance...

FYI the pcv valve for the RB20DET is PN 11810-45V00

Checking with Shay at Nismoparts for availability

Well you don't NEED vacuum.As long as your not pressurizing your crankcase.Drag cars run vacuum pumps to squeeze a little power out. I belive it reduces wind resistance or something.

Google it if your interested in it.
