Okay, go ahead and flame me but I know some of the members have experience with small block Chevy motors. And no, I am NOT going to join a Chevy forum to ask one question. With that said, the early SBC (early/mid 60's) PCV oil separators that went in the lifter galley, how effective are these at removing oil mist? Please don't ask why I want to know, I'm having one of those moments!
