Idle >14psi
2,000 RPM >43psi
That helps understand the oil burning issue. Imagine what the valve stem seals are seeing...

Err......Valve stem seals don't see ANY oil pressure... Just the cam bearings, then the oil drains to the sump.

Isn't the oil under the valve cover under pressure? Maybe I'm mistaken, but I'm under the impression that everything under swimming in oil, under pressure...

Not "crankshaft bearing" levels of pressure, but under pressure none-the-less.

Nope...Oil is Just pumped up to the the bearing journals just like the crank journals really (except for the oil that gets spewed across the garage to keep this on topic), it squirts out, gets flung around a bit and then drains back to the sump. Pop off your oil fill cap while the car is running and take a look....
