That engine is only 37K miles but it's also 27 years old. Go down to the auto parts store and get a vial of oil leak dye check. Clean the engine as best you can with some brake cleaner and rag. Add the dye, drive it again in a normal fashion. Jack it up and use a black-light to see the new oil traces.

I think with the engine's age you may find the oil is really coming from the large o-ring seal behind the cam sprocket. Those o-rings don't stay resilient forever. It is not logical oil can get out here and go toward the driver but it does because of the airflow and castings.
