Whoa, your post is making me realize I'm a bit over my head here.

First, the routing. There is a red metal box coming out of the driver's side of the block, forward of the distributor. I take that to be a flame trap of sorts, maybe with some sort of valving (is that the PCV?). Looks original. A 1/2" ID rubber hose comes straight up from that to a T fitting. From there, one side of the T goes to the brake booster, and the other goes to the manifold. That's the extent of the system best I can tell.

Observations: I've unplugged the hose from the brake booster. It pulled a wicked vacuum.

Is the idea that the manifold should pull a vacuum under normal conditions? What is the flow of air past the PCV valve? Is there normally a slight crank case vacuum? The source of my question is trying to figure out where and how that PCV valve functions. Is it in that red box?
