Oil residue around Intake Manifold

[Roc14]

2011 LX woth 210k miles. Popped the hood to inspect the engine and found oil residue around passenger side intake manifold. The weird thing is its on the intake manifold where the bolts are? You would think the residue would be below? I pulled the pcv valve and it's good. Ordered an intake manifold gasket. I don't see the cam overhead leaking anywhere.

Any ideas?

Thanks,
