Re: How to route the PVC System
PCV... Positive Crankcase Ventilation
You need to run a PCV valve in the passenger side valve cover that attaches to a vacuum source (like the port in the back of the carb for example), and then a breather in the drivers side valve cover that allows fresh air in. EZPZ Gary

Re: How to route the PVC System
Also, if you have the original air cleaner spacer and flame arrester, you can hook them up for a closed PCV system.
Under the fuel inlet on front of the quadrajet is the vacuum connection for the PCV valve. Here is a thread where some of the connections and parts are discussed as I was working out the system on my truck: http://67-72chevytrucks.com/vboard/s...d.php?t=706115 Great detailed info here from RichardJ: http://67-72chevytrucks.com/vboard/s...d.php?t=711484 |
