I have an old type 30 model ingersoll rand air compressor. It has not run for years, we just wired it up and ran it for about 5 minutes. After that, I thought I better check the oil level... There does not appear to be a site glass, how do I check the level? I pulled the filler cap and cannot see any oil

Alot of the older units did not have a sight glass. They had a dip stick on the fill plug. Over the years they broke off or the oil fill plug was replaced with a newer type that does not have the dip stick. To answer your question dip stick or not I always fill with oil to the bottom of the threads on the fill plug. You should remove the plug and check the oil level before each use on and older unit like this until you have a good handle on how much oil it uses. you may also be able to remove a plug usually on the front of the case lower left side and install a sight glass or low oil level switch. Have a good day!!
