The Stovebolt Site Forums The Shop Area Engine Shop Adding a PCV to a 60's engine with non-PCV valve covers.

Thank you for all the replies and especially the link to the older thread.

Looks like the setup I created mimics the original intent of the California retrofit kit pretty close. I just placed the PCV a little farther back in the system. The PCV valve I have is designed to allow airflow from the metal end toward the plastic (hose) end, while blocking airflow in the opposite direction in the event of a backfire through the carb. I believe this is the correct direction of airflow for my application.

The airflow in my set up is outside air is drawn into the engine via the breather on the Oil Filler Tube, passes through the filter in the cap, is drawn through the lifter valley and exits the block through the road draft tube hole. There it goes through the PCV and goes back into the intake manifold via a vacuum port on the back of the carb baseplate.

As was stated in the linked thread, figuring out what previous owners did is a lot of the fun of these old trucks.

Edit: I checked the PCV valve I have. Numbers on the side are 2072. I can suck on the hose end and air flows. I can blow into the hose end and air is blocked.
