Default Re: PCV valve good idea?

I modified a reproduction Air Maze by putting a copper fitting into its throat. I also took an accessory draft tube that was on the breather and replaced its metal flex line with a rubber hose. The hose was connected to the Air Maze. No PCV was used. This setup did reduce leakage from the rear main, and it ran really well. I am demanding of my engines to produce power, and I did not notice any degradation in power. The engine had Motorcraft TT10 Spark Plugs and they ran clean.
