I personally wouldn't bother, the original system is there to stop buildup of blowby gasses and moisture in the engine and it works well. The pcv valve can take alot of stick, it's designed the same way as the hks ssqv the more pressure behind it the more it seals when on boost. But if your going to do it, it need to have the air dragged through it as it won't do it by it's self.
