Catch Can

I am building a catch can for my 90 Eclipse to catch the oil, I don't like it going into the intake.
I am venting the side of the valve cover but was wondering if it was safe to vent the PCV valve into the catch can as well?
Do I just run a line from the valve to the catch can or do I have to replace the valve with something? How then do you recomend closing the opening that the PCV valve was running to?

THANKS
