Possible Intake Manifold Gasket Leak? 2013 Coyote

[S197cadeb]

was doing some detailing on my engine bay when I noticed a possible leak coming from under my boss 302 manifold. Had a couple of my buddies look at it and told me not to worry about it.....
Thought I’d get more opinions.

The spot is dry. Not a very big spot but nonetheless... I can’t explain why it would be there unless it leaked from somewhere. Oil looks fine.... looks great actually. I’m about 3500 miles in and the oil isn’t even black.
I’ve attached some pictures just to give you an idea.

Should I be worried???

What can leak from an intake manifold on a 5.0 Coyote? Answer is vacuum. Unless you have a huge issue with oil being pulled into the intake from the PCV valve. Outside of that it is simple to inspect for a vacuum leak. A can of carb or brake parts cleaner can pinpoint the source. A vacuum leak will not typically show up externally. Clean the area around the suspect "leak" and re-inspect after a test drive of 5 miles or so. If something is leaking externally (which is hard to do when the intake is in a vacuum most of the time) it will show up shortly.
