The pipe is definitely tapped into the lower backside of the intake manifold, and it bends down towards the back of the engine block, where it screws into another large female fitting that is tapped into the crankcase immediately to the left of the back valve adjustment cover.

The fitting pictured is the piece nearest the intake.

I spoke with Frank from Northern Illinois, and his guess is that it's some type of retrofit using the engine block fitting where the crankcase open vent pipe might have been.

The car is an original Cincinnati, Ohio purchased vehicle, and I don't know why the adaption was made. I have read a lot about bad press or the open crankcase vent tubes on older cars; but it would seem that there would be some info someplace on the web if this is a primitive PCV valve.

Bottom line = the part in question isn't functioning, as there is a hardened dark tar on the inside of the intake manifold from this breather tube. It appears to have a spring mechanism; but there's nothing to stop (or limit) the flow of oily crankcase gases.

I need a time machine or a crystal ball.

Thanks !
