Don, the PCV I added to the 235 didn't make much noticeable difference in the running. At least not yet. It runs leaner...and I expected that, but the engine vacuum isn't much lower. I used a 3/8 inch hose from the intake manifold to the modified crankcase draft tube and then I used a 1/4 inch reducer at the valve cover because I wanted more negative pressure inside the engine. It seems to be doing ok and as the engine has been rebuilt there's not a great amount of blow-by anyhow. Good luck.

I’m not really experiencing any problems. Wasn’t sure until this afternoon but it turns out my rough idle is caused by a bad plug wire. I also adjusted the idle mixture a smidg.
Thank for your reply, Don
