I noticed a small amount of black oily fluid where the upper composite intake bolts to the manifold on the left side? Any info on the cause and what it is leaking from there ??

Crankcase vapor - basically oil and condensation

You might have to replace that oring under the intake if it's leaking ccv vapor it's probably bleeding boost as well

It doesn't look like it's a big leak otherwise it would be wet with oil. It'll probably get worse over time and you'll just have to replace the o ring

Is this a common issue? Has anyone else experienced this?

It’s hardly an issue. Just take it back to ford and tell them to fix it or spend the 2$ and 7 minutes to fix it yourself. Hell, check the bolts, probably just need tightened.
