Default Oil leaking into maf????

I have a issue with my ta its a 02 ls1 randomly started leaking oil from the intake into the elbow where the intake and maf connect. What could be causing this? I changed out the pvc already and no fix.. The car was turned on every once in a while for the last 2 years doesnt get used much if this helps any...

The "makeup air" side of the PCV is unchecked and flows
in reverse at WOT where you have crankcase positive
pressure and inlet trace negative pressure. A catch in
that line could help you out.

"catch" means oil catch can. Do a search for catch cans or PCV line. Results from the search will explain everything needed.
