Isn't that crankcase ventilation?

This engine, once upon a time, had a weber.  The manifolds and carburettors=
 have been switched out.  This manifold came from a later, pollution equipp=
ed car.  Bad choice on my part but at the time I didn't know better

As you can see, there is crank case ventilation going on. =20

I need to stop this hole.  The bolt in the hose will work for now but I nee=
d a prettier permanent solution.   =20

What are the O.D.s of the flare of the fitting and the next bit? Dorman
sells rubber caps (5/8", 3/4", maybe others), and might have one that could
be slipped over the end and secured with a hose clamp. I found a few at
Summit Racing, sold as cooling bypass caps.

Plan B might be to cut off the flared bit and find a cap that fits that
part tightly.

Plan C would be cutting the fitting at the manifold, threading the hole,
and using a tapered plumbing plug.
