Question Possible Oil Leak Sources

Assuming the rear main and the cam welch plug are not leaking.

Factually, their ain't a drop of oil on the flywheel inbetween the motor or out on the clutch surface. Distributer boss and oil sending unit and valve covers not leaking either.

I have a drip of oil that runs down the drivers side. It wets the bottom of the oil pan between the drain and the rear. It mostly drips off the wing of the oil cannister boss and seems to migrate over to the oil pan. Thought it was the cannister leaking but there is fresh oil on the drivers side spark wires where it go's thru the loom above and to the left of the oil cannister boss. C

Any welch plugs on the high left side? This one has the cannister oil filter, possible leak at some type of gally pipe plug near there?
