Bob,
Thanks for the info. I've got mine installed, but haven't driven the
car yet - rebuilding a LCS pump for it. I machined a 5/8"-20 - 3/8"
barb fitting to screw into the front manifold. Added six flats for a
wrench - Whitworth so I can be annoyed with myself at some future date.
To go from the 5/8" diameter on the valve cover tee to the 1/2" diameter
inlet on the PCV valve, I shaved the ID of a 5/8" hose and the OD of a
1/2" hose on the lathe and glued them together with rubber cement. 3/8"
hose connects the PVC valve to the manifold fitting. Added hose clamps
at each connection and soldered the hole in the oil fill cap.
Cheers,
Bob Haskell
