You have the basic idea right. If your carburetor has a PCV port on it
you should attach one end of the valve to the carb (probably via rubber
hose). If the carb doesn't have such a port many after market air
cleaners have one. The other end of the PCV valve hooks to a valve
cover or in the case of my GMC (Pontiac) V8 the valley cover. Many PCV
valves have arrows on them showing the proper direction of airflow. The
arrow should point to the carb.
Don't forget that the system needs somewhere to get fresh air into the
crankcase. A breather on the opposite valve cover will do. In the case
of the GMC (Pontiac) V8, there is a breather on each valve cover to
supply fresh air.

Subject: [oletrucks] setting up PCV
Hi,I'm looking for some help for setting up PCV on a V8. I know the
basic
concept, but I don't know how everything goes and where everything is
connected.
For instance, do I just go to Pep Boys and buy a pcv valve and plug it
into a valve cover? Do I plug the other end into a carb port?
thanks for the help.
