Mr. Hall gave you the exact answer. Yes they can. The splash oil lubes everything just fine.
The trick to a long lasting 915/930/G-50 box is this:
They don't like speed shifting. Smooth is the way. G-50s are more forgiving with their GM style synchros.
They don't like short shifter kits.
The synchros won't work well with anti friction additives.
Start an engine with no oil in the gear box and kiss the needle bearings good-bye in 60 to 90 seconds
Use limited slip gear oil with LSDs. Swepco is the best for any Porsche gear box.
Don't downshift into first unless you are under 15MPH.
Don't pop the clutch to burn off. Get off the clutch completely and then you can floor board it and burn tires to your heart's content.
