<VV> PCV by model year; Was: 1962 Vair

[Doug Mackintosh]

No, the 1962 model year Corvairs (and other cars) sold outside of California had 
a road draft tube, no PCV. PCV came with the 1962 model year. 


The November 1962 Car Life magazine new car issue says:

"1963 will not not go down in history as the year of the big change but when you 
look beneath the superficial face-lifts, the total number of engineering 
developments is rather astounding. Highlights of the year's new models include:

...9) Positive crankcase ventilation for all cars"

Page 7-6 of the 1962-1963 shop manual supplement states:

"All 1963 Chevrolet engines have either "positive" or "closed" positive 
ventilation systems utilizing manifold vacuum to draw fumes and contaminating 
vapors into the combustion chamber where they are burned." 


It goes on to describe the system and proper maintenance therof. 

Bill Stanley responded to this:

<<Anyone know what year the PCV system was made standard equipment on  
Corvairs? >>

With this:

<<I hope someone who knows the definitive answer to this question will post  
it here.  Until then, here is what I believe off the top of my head:  
Positive crankcase ventilation was standard on CA cars beginning in 1961 and on  

all other U.S. cars in 1962.  For model year 1963 only, the crossover tube  
connecting the two air cleaner housings on a Corvair contained a clip to 
hold on  the PCV assembly.  I recall at the SCG (stock Corvair Group) event at 
the  Ventura convention looking over a stock, low mileage orginal '61 car  
assembled at the CA plant that had PCV.>>
