I did my test drive it was fine gave the car to the owner. After 3 days we found the car still smoking and when I did check I found too much oil on the intake manifold. What must be the problem?

Hi:

Is the oil possibly coming from the valve cover? That's the only thing above the intake that can leak oil externally. I attached a picture of the engine on the intake side and highlighted where I'm questioning the leak may be coming from.

Let me know.
