Just because there is a dang valve (or orifice) there doesn't mean the
system works like a positive ventilation system ... just something to
keep CARB happy so they could sell Corvairs in Californ-e-a.
The real question being, since it really doesn't work, why did
penny-pinching GM spend the money to design and implement it? Or, maybe
it wasn't "designed", but simply "implemented"? Were sales in CA 'that'
important? Well, it wasn't a road draft tube (which actually works
better) ...
Don't get me wrong -- a properly designed and implemented PCV system is
a boon to internal combustion engines -- improves longevity and can
improve performance (also helps control crankcase pressure, and thus, by
corollary, oil leaks) -- too bad GM didn't put such a system on the Corvair.
My initial post concerned the spelling of the acronym. And then, failing
to keep my mouth shut, I posted further.
Or, maybe the question was for a different Bill?
