Kiwinui

Hi everyone im new here the names kiwinui but you can all call me kiwi..any whoo I was wondering if any one can help me out with the pcv system on my 2002 subaru wrx sti ej207...sooo I'm a bit confused on different views and setups that people run, some say block the intake side of the pcv also cap the end off on the block side will this do the engine any harm?also dose the pcv have to tee in to tub of duct?any help would be much appreciated also pictures of setup would be great..I plan on running a catch by tee'ing head breathers together..last question what is the breather next to the head vent hose and what can be done with.. sorry for the lengthy write up just want to cover everything..reason why I ask because I'm in the middle of doing a flipped intake manifold and looking for other clean looking options..
