Oil in my intake manifold?

Oil in my intake manifold?
I've had my 2006 ever since new. I've had to clean out the throttle body for the third time now because of idling problems, and it always runs great. While I was cleaning the throttle body tonight, I shined a flashlight into the intake manifold and WHOA! ...It is completely wet inside with oil! I stuck my finger in past the butterfly valve and brought it out with a good coating of dirty oil. Is this normal? My car runs great, always has. (Well, except when the throttle body gets dirty and it idles low.) Should I be concerned?

I'd say it's normal that's what the PCV is supposed to do, that's also why people get the oil separators.

It is normal in Ford's eyes/design, But not mine. The design of the system is to pull/recirculate the crankcase vapors (hydro carbons from blow-by) back into the engine to be burned. This is for pollution and reducing sludge build up etc.
The vapors are fine, but we don't want to introduce oil in the intake system and burn it! You can read more about oil separators and affects of oil here.....
