<VV> Advise on PCV needed

[Bryan Blackwell]

I've read that a PCV system can slightly improve ring sealing by reducing the crankcase pressure, but the primary benefit is emissions.  One other minor consideration is that it isn't correct - if the current owner cares at all about resale value, it would be on my list of negotiating points to work the price down.

I am wondering if there is any mechanical disadvantage to this. I have the parts to put it back to stock to feed to the air cleaner and balance tube (with PCV orifice). I don't see how it might affect engine performance, but would like some advice, to be sure.
