Could I run pcv of the intake manifold instead of the carb ?

Can't you just run it to nowhere? I mean isn't the PCV just to release crankcase vapors? Can't it vent to the atmosphere? Of course it's bad for the air, but I live in iowa so I don't care that much haha.
As said, you are just asking for oil leaks and oil in the wrong places (like down the intake valve guides).
