The answer is - - - It depends. All 1960's had draft tubes. That is  
correct. 1961 and 1962 Corvairs delivered in California has a Positive Crankcase  
Ventilation (PCV) system installed, using a valve, recycling much of the  
unburned fumes in the crankcase. (Not sure how positive it was, but it did 
vent  into the engine inlet system.) 1961-1962 Corvairs delivered outside of  
California still used a draft tube. All 1963 cars used the PCV valve, 
1964-1969  cars, except air conditioned cars, used an orifice system and still, 
pretty much  had crankcase recycling. 1964-65 Air Conditioned Corvairs still 
used the 1963  valve system - as well as the twin air filters.

Was the  1960 the only one with a draft tube?
What did the '61  use?
What did the '62 use?
A friend of mine has  a '62 with a '62 102 engine , but it has a draft 
tube? This  does not make sense to me. Also the intake duct to the two air  
cleaners has clip on the top on the passenger side, like to hold a  PVC valve 
and accompanying  hose.
