Other places on the internet aren’t so cool to deal with

In 1965 I had a '55 chevy with a '56 Cadillac engine. Did not build it, it was sort of high school butcher job.
But that old Cadillac had enough torque to snap the chevy axles every single weekend...
They deserved each other, I gave it up for a '39 Tudor after a few months!

I know what you mean. For what it's worth I had a good look at my own PCV setup. There was a slight vacuum leak in the hard plastic elbow that mated with the valve itself. At least with the hose sitting on my work bench. So I swapped in a new rubber elbow and it's all good now. Didn't really change how it runs but who knows how old the original plastic piece was.
