Do you see a metal line "ahead of the carburetor" in the photo you posted that crosses the valve cover? That is the line that draws air through the PCV valve (which is threaded into the standpipe) and pulls it into the intake so the crankcase vapors can be burned. All PCV systems work the same way. There MUST be a flow of air through the engine. The rubber line sources that air from the "clean" side of the air filter. That line puts air INTO the engine- - - - -vapors DO NOT come out of it. Somewhere, from one of the shop manuals that people like to post pictures of, there is a complete diagram of the OEM ventilation system that shows the entire airflow of the PCV system. I simply do not know where to find that illustration.

We're like a bunch of blind men describing an elephant by touching it. One grabs the tail and says "Its like a rope" Another grabs the trunk and says "It's like a snake" Another touches the side and says "It's like a wall"- - - - -etc. Nobody sees the whole picture!

Dad's picture shows the PCV valve- - - -it's between the elbow going into the standpipe and the metal line crossing the valve cover.
