There is a spec for vacuum at the oil filler cap. It Has to be read with a manometer as a regular vacuum gauge is not calibrated fine enough. I do not know the spec but if it exceeds the spec then the AOS is suspect. This info has been posted by member "JFP in PA" so if one does a search you should be able to find the info.
