49 state did not have the vent hose from the oil filler cap to the air cleaner. Being from CA you might still be required to use it. The hose from the PCV valve go to a port in the carburetor.
Well, my car will not be inspected, no smogging on it. It is too old. Then, well, isn't the idea that the engine will pull in the fumes through the PCV valve and burn them ? So I sort of fail to see that it is such a benefit with the hose from the oil filler cap to the air cleaner. I mean, it will not help when the engine is running since it is suction there anyway, and it will not help when the engine is stopped either, because then the engine does not pull anything in, neither from the oil filler cap nor the PCV valve. I have the feeling it is most for looks. :)
