LOL some people just love going against the grain for no other reason than to do so. The PCV system was oringally designed to meet emission and environmental standards. Does it hurt the engine with that little amount of oil getting into the intake/runners/valves? Probably not per say.
I dont know about the rest of you, but after about 100k miles of that little amount, I would think its bound to become a bit clogged/dirty. I can just about promise you if Ford didnt have to have that system in place, they wouldn't. Dont think just because Ford did/didnt do something, means it doesn't hurt/help the engine and performance.
