Ditto the right side, except that it was NOT full of oil. Not "dry", per se, but didn't drip at all when I unseated it.

What's "normal" ?

So to clarify, the left (bank 2?) cam plugs have been blown out and the scavenge pump is possibly not moving oil? Is this also the bank that the camshaft plug may have blown out on? These are not positive displacement pumps. They are rotor. gear pumps. Possible pump damage or blockage downstream at de aerators to sump? Bank 1 (right) could be dry due to AOS directly attached there and most/all oil going to intake?
