To PCV or not to PCV

["alfaki" <alfaki@bellsouth.net>]

Ok, I'm a little confused about the PCV function vs just a plain tube to the
air cleaner or carb.  What is the difference in function?  Which should go
where or would it be best to have 2 PCVs?   I've removed most of the smog
crap off the motor but want to maintain a closed system. thanks in advance
to anyone that can clear this up.
