Engine Bay Clicking When Key is in on Position

[dsm1212]

Alright So when I turn the key to the second position I will sometimes get a clicking sound in the engine bay it doesn't do it right away probably every 3-5 min. It kind of sounds like if you were to stick a ruler in a fan that was turning off and stopping the blades with it. I checked my radiator fans and they are not hitting anything it sounds like it is coming from underneath the intake manifold or somewhere around there. It also does it when im driving, but i only notice it when i am going slow with the windows down can't figure this out!!
