What would cause a steady drip of oil only when started?Not the oil filter, oil pan gasket, or no valve or cam covers leaking.

Anywhere there is oil pressure. Not sure if this has oil cooler lines, but that would be a common point on many. Oil pressure sending unit maybe. Main seal.

You need to get good lighting use mirrors if needed and start looking.
