Someone said that around 200-220k the fuel pump doesn’t work as well or not at all
It won't cause blue smoke no matter how bad it is, and it can only cause loss of oil by overpressure that fills the crank with gasoline. Your crank was empty, not overfull and thin. I'm afraid you're barking up a completely irrational tree.
On the other hand, a bad PCV or improperly-routed PCV plumbing can definitely cause catastrophic oil usage. That's the right tree, and if you don't find anything there, then you simply bought a bad engine.
