The check valve is a two way valve. It opens up bigger (allowing more flow) in one direction than the other.
The hole in the PCV box have the same diameter/flow going both ways (so to speak).
I have no clue if this is the final on the PCV/oil leak/cylinder head bolt saga.
At least, now Saab mention in their technical litterature that the cylinder head bolts were not properly anti friction treated up until a certain engine number in 2001, and that together with tightening process problems in the production plant could make the head bolts come loose.
