This just started happening yesterday. Took the car out for a drive (first time in two weeks) and when I came back, I noticed a few tiny pools of oil on top of the motor. These definitely weren't here before the drive as the car, to include the engine bay, was freshly detailed. Some of them aren't visible in these photos because they're hidden behind the intake runners.

The car runs great; oil pressure is consistent. Just trying to guess what the possible cause is before I go take things apart...

My first thought is the valve covers. My second thought are the four center intake manifold bolts.

 

I agree

pull the 2 center intake bolts, clean them and put a small dap of silicone on the threads and throw some valve cover gaskets on there for safety.
