But I think what got this one was that the head's oil drain holes plugged up, and so the pressure-fed top end components likely were oil starved. Bottom end maybe got enough pressure - I didn't ever see an oil light except just at startup, as one should.
Just the opposite. If the oil drains were pluged that would trap oil on the top end which in turn would starve the bottom end.

High oil comsumption can be caused by bad valve stem seals, faulty pvc valve and or bad rings.

Do a wet and dry compression check to see if the problem is due to rings or valves. Or use a leak down tester.

It would be best to diagnosis the exact problem first before making a decision .
