Assuming your 85 is the same as my 87:
There are two hoses that make up the pcv system:
1. Hose/pipe from valve cover (black 90 degrees plastic end piece) to throttle body (hose / plastic/ rubber pipe) on passenger side; and
2. Hose/pipe from valve cover (pcv valve) to intake manifold (hose) on drivers side.
Passenger side picture.

I was replying to Lemme ; not you
Follow the line from the canister to the purge valve and then follow the purge line
from there (if the line still exists )

Cheers. Didn't know there was a vac port on the TB. Strange that the 85 diagram doesn't show a vac source at all for the purge system!

Not used to reading vacuum diagrams. They are a bit like electrical circuits only different.
Thanks again.

My '86 (which also has cast iron heads) looks like the diagram in post #3. The aluminum tube Ts at the end and one hose goes to the charcoal cannister (wraps around the front of the valve cover in the pic). This is what my driver's side looks like:
The rubber hose going into the throttle body is not a vacuum connection. It just picks up filtered air and feeds it into the crankcase. The vacuum is on the PCV valve side. The passenger side:
