Perhaps a canister whose inside is filled with oil droplet baffles should be pressed into the hole in the valve cover and then the PCV inserted into the top of the canister?

There has got to be an engine valve cover already designed that does a superior job of keeping liquid oil drops from the PCV.
The PCV should only suck away gases.

The boiling point temperature of high quality engine lube oils should be way too high.

I am sitting here wondering if the
“AMC rocker arm oiling design” generates more oil droplets than
the “better high rpm stability” Chrysler design shaft mounted rocker arms?

Oil spraying out of 8 pushrods might be the “root cause” ?
