I think for both you guys, welding a nipple for a PCV or setting up catch cans is the only solution.

At light load, you guys are clearly pulling vacuum, so that means you need a regulatory valve to fix.

Either fix will do, because it will result in a closed system -- than means no more unmetered air slipping in.

The only other solution I can see would be trying to have a PCV before the open filter? Then the crankcase filter becomes a one way vent.

Just throwing out some ideas to try...
