Since California no longer requires smog inspections for pre-1973 vehicles,
my '69 Sprite is no longer wearing its air pump, check valve, gulp valve,
etc. Hasn't for quite some time, actually (like...well, a lot of years). My
memory tells me there was a PCV valve in there, too, sitting on an intake
manifold fitting that was a T, with an air hose from the gulp valve so that
air would be dumped/pumped into the manifold on the overrun. That fitting is
gone, blanked off, tossed with all the rest of the smog stuff. My question
is, should I be running a PCV valve? The only crankcase ventilation still in
place is a hose off the timing cover can, which runs to a black plastic
T-fitting which splits and runs to the carburetor bodies, just under the
dashpots, before the butterflies. This, I think, is original. So...should I
find and re-install a PCV valve on a (non-T) fitting back into the blanked
off manifold port?
