I see your join date and post numbers....Far be it from me as a new member with only 10 years playing with these birds...but I have a few years before with old cars....HA>>>if it ain't leaking it's empty. All these heads potentially seep. YES...Torque the head according to the RED BOOK sequence and do it often. Yes they drip oil under the transmission, yes they occasionally piss gasoline from whatever, yes they do weird stuff...they are all almost 100 years old.... drive the old gal and enjoy...don't look for "ominous" problems.

These are basically lawn mower engines..If you had a good mower in the day, you checked the head bolts every season, changed the plug and blade....changed the oil and off you went.
My friend, change the oil, check the head, READ THE OWNERS MANUAL for the generator gets some oil, the distributor likes a drink, and the rear banjo likes a good tightening...the Red Book has a maintenance schedule....don't over think the easy...but don't ignore the simple preventive.
