I’m trying to put it back to stock but trying to avoid throwing the bank at the problem. I’m a believer in the PCV system but I’d like to see if I can find a way to do it using my existing valve covers, which I’m trying to do.

Next week I’m going to install a PCV valve in the left side where the knock out is and put a oil cap that fits and seals where the breather Is now (on the left side). I’ll move the breather to the right side. If that works Then problem solved. Otherwise I’m shopping for valve covers.

Thanks for all of your input. The diagram you posted helped simplify a system that is frequently misunderstood.

The only negative thing about using a vented valve cover breather not attached to the air cleaner is that over time, you'll get an oily residue on the valve cover from the little bit of normal blowby even a healthy engine has. And that won't hurt a thing it will just make a mess after a while. Why are you bucking the system and not just wanting to put it back stock?
