Old thread dig but who cares.
Considering purchasing a Perrin Air Oil Separator. Has anyone had anything to do with these on an RB? Was thinking of setting it up like this, both rocker lines in to can, pcv line to manifold blocked and rocker line from pcv valve to can, return from top of can back to intake and oil drain at base plumbed to turbo oil return. Thoughts?
Engine is rb25 and has been rebuilt to Nissan spec with internal oil control mods so currently healthy. I would like to keep it plumbed back and low maintenance if possible. Engine is in a RS4 stagea and is used daily with occasional drag use. No track days or gymkhana events to worry about.
