    more info is needed … as to where the oil shows up.  sometimes  a simple airline crack from freezing  will let oil seep out over time .

    has suggested the best is to pump some air in the GC  ..a soapy water  spray can be  used also … testing like a flat  tire will show bubbles where the problem is.

    here is  cheap Amazon tool  I  use but you need the  3/8 inch 16TPI  adapter to  screw in the lower oil hole.

    you can use it to also  vacum test the GC
