thanks for the input guys, is there a specific aftermarket PCV system anyone recommends for the 235? I'm still confused how the evac system was setup before I did the overhaul, I didn't find any PCV valve, or draft tube. valve cover has filtered oil breather and a tube that connects to the stock air cleaner (which im discarding) but i don't recall anything connecting to the crankcase itself. if there was would it be near the draft tube plug or somewhere else on the block?
