I have determined the oil leak seems to be coming from around the oil pan gasket or possibly from the rear (car rear) from a tube or pipe that is fastened toward the rear by a bolt. This is behind the engine. Possibly there is an o ring or gasket there that is leaking. I was able to tighten this bolt a half a turn or so but still seems to be oil sepage there. The leaking oil gathers right at the drain plug which I also replaced with a new Ford plug. I added a gasket sealer to the crankcase oil and that did not seem to work although the drip may have slowed either from that product or the tightened bold. All the crankcase bolts seem tight.
