if I understand you correctly it is the normal pcv taking air for pcv from inside the main air cleaner mesh ( so air is very clean) and admitting it to the engine? sometimes blow by is sufficient to overcome the pcv and blow oil backwards ( pcv is not pulling air anyway due to no vacuum if your foot is in it ) and thus get the inlet fitting oil soaked , sometimes inside the air cleaner too .
All that is kinda normal if ugly looking and the oil and air are clean . Pcv normal flow is very low it is not restricted by this .
I’d leave it alone unless damaged or something ? A new one will be the same within weeks.
That said and not sure it fits but I have a 78 dodge 318 pickup doing the same thing . Don’t like it — but way it is . Some fittings push into a rubber grommet and some have a 1/4 turn lock like an oil fill . I believe mopar performance sells them for its own valve cover line but may not fit ,— but must be common in junkyard ( Murray Park?)
All production used this some thing years after california ? I wonder what year the pvc started ?
A good thing , prevents sludge build up inside by pulling junk out . . Hot heads sells a kit to put pcv on 392 on the valley pan where the draft tube goes , I have used those on several cars at rebuild
Good luck !
