I decided to build a PCV hose out of the old one. You can see I put a smaller hose inside the 5/8 hose which fits the fitting on the back of the intake manifold.
I then fit a plastic PVC valve elbow I had in my stuff into the 2 hose piece. Then fit a little larger diameter hose over the fat end of the elbow. The original black tube then fits tight into that hose.
I used a heat gun and some spray to make assembly easier.
Voila.
I put a rubber plug over the 'mystery' vacuum fitting at the base of the throttle body. All I can think of is it is used with a heated PCV configuration. The original plug may have gotten knocked off when I was wrestling with the plugs and COP coils?
