I have read a few threads telling that the PCV valve goes in the intake manifold behind the carb with a hose connecting it to the front on the carb. That is fine, the same as what is on my 400. My question is, what goes in the hole in passenger side valve cover o No: Is that for a breather, or another PCV valve to hook to the air cleaner o No: Thanks Dan :3gears:
On a stock 68 350 with original air cleaner, you would have a formed rubber hose attaching to a metal hose barb into the valve cover, running to the air cleaner.
