68 z28 correct pcv valve

[169indy]

Here is my as found 746C on my Dec Los Build. I suppose it could have been changed out over the years, as in the Machined -vs- stamped formed versions. As an additional comment or question, Can these things be cosmetically restored via a cold brite zinc plating process w/o detrimental affects to the check valve ball inside?

I would think it would be easy to zinc plate them. It is air-tight in construction so with some care to plug the ends with some tight fitting rubber plugs that would prevent any chemicals from getting to the interior. Just to verify, plug one end and connect a mighty-vac to the other end and see if it holds vacuum. If so you are good.
