PCV system oil catch (7/'06)View all 3

Basically, is just an air-compressor water/air separator with 1/4" NPT 3/8 hose barbs attached inline of the factory PCV.

I have it mounted on the valve cover (see pic)

Material I used:
~2ft fuel/oil 3/8" hose
1 1/4" NPT air-compressor inline water/air separator
Teflon tape
A small ~2" strip of 1/2" adhesive backed foam insulation, used to protect catch bowl from cracking against valve cover.
