What is the current mechanism for pressure leveling between the two valve covers though ... through the block? Don't think so. The PCV is designed to relieve pressure that is accidentally placed on the valve covers by the block. Valve covers aren't designed to manage pressure, they are usually just light stamped steel.
A crossover tube may be overkill but with our oil consumption problems, it's an easy solution that may have large benefits. I'm just proposing that I'll be the guinea pig to try it out. The trial will just be to get an aftermarket oil fill cap, drill a hole through it, run a hose from there over to the catch can, drive it for a month or 2 to see if it helps ... easy peezy!
I'm already running an oil catch can on the Amigo & cut the oil consumption in half. Next I'll try the crossover tube to see what that does. Replacement engines just don't seem to be the bestest solution to our oil consumption problem ... there's gotta be a better fix.
