Hey guys. I'm trying to eliminate the PCV hoses and aftermarket oil separator on my car because I think they're an eye sore. I've seen guys running the breather on the valve covers and I was just wondering 1) does that mean I can eliminate the rest of the PCV system including the PCV valve, and 2) does any oil make its way past those breathers? I'm worried about them being messy. Thanks in advance for any and all help.
