Well today i took a look at my car blew thru the PCV hoses and you can hear the oil moving in there when i blew. So i did a search but this was not really answered as many members were split in half on not to do it and doing it.

So is it safe to plug the PCV hole, and have 1 breather on each valve cover? Im tired of these oil **** problem. While im at it im goona buy new oil pan gaskets. And maybe timing chain cover gaskets, im gonna make sure its not leaking for sure tru there first.

So yes delete it or no???
 
I wouldn't eliminate it. Vacuum in the crankcase is designed to help the rings seal better, as well as clear oil vapors. Plus, if there is vacuum in the crankcase, there is a better possibility of seal NOT leaking because there is slightly less pressure than atmosphere to pull the oil back into the engine.
 
I'm running a valve cover on each breather and a gutted pcv valve to a catch can. Works great, and no more oil in the intake. A vacuum pump would be the best choice, if you deleted your smog pump you can place it there.
