Could this leak be because the PCV valve was backed up? or do I have a bigger issue with the IRIS valve?
I do not know of any bushing/seal/O-ring to seal the factory shaft IRIS shaft.
However if you replace the IRIS O-Ring, that should take care of most of the vacuum leak/oil leak.
Otherwise it will need an IRIS valve.

For the record, I have never bought a new one from Subaru.
