Chicago Pneumatic air compressor, blowing oil

[RON MARSHALL]

Chicago Pneumatic air compressor, No.65917, 125 CFM, RG-2 ,rotary vane compressor ( year built 1959) gas engine , recently inherited this machine, runs fine , blows lot of air, though lots of oil also . unfortunately no manuals or parts list . checked with Chicago Pneumatic and no help from them. after some research,lol,lol, a lot of searching, things done so far : drained approx 8 gal of oil (seems like a lot) pulled the oil separator filter ( unusual arrangement) ,in the process of cleaning all the other filters and return tubes that i can find.
any help would be appreciated.

Overfilled, scavenge line plugged, air -oil separator bad ( plugged, saturated, ruptured).

thank you , working on all those issues , except the separator, not sure what to do about it , it just perforated plates and some kind of fibrous material stuff ( kinda like fiberglass ) between the plates.

It should have at least couple of layers of som kind of media, at least on outside.
If it is gone - that’s your problem, lady!

the biggest problem is to find new one!
There’s also should be a tube going down almost to the bottom of the filter-separator, that supposed to suck the oil that did manage to go passed the separator back to air end.
