oil behind throttle body?

Hey guys. Just curious, Is it normal to have oil behind the throttle body. Not on or in the TB but behind it in the plastic box shown in the pic. Jeep runs great, was changing plugs today and I took off the TB to get at the plugs easier and in the black box the TB attaches to there was a good coating of oil in there.

This is a 2.4L engine.

Not sure, can't believe no one knows or hasn't responded.

On my old Dakota, it was perfectly normal to have a thin layer of oil coating the intake if you looked down inside your throttle body, however, if the oil was kinda puddled up in the bottom and not just a coating, that was a symptom of a blown belly pan gasket. So I'd say you're normal if it's just a thin coating.

Wow, that's the first time I've seen a photo of the 2.4L engine. It sure is different looking.

I noticed the same thing on my 4.0 when I cleaned out the throttle body recently . . . when I opened the flapper, I and looked down inside there was what looked like a combo of oil, moisture, and dust . . . had me pretty worried . . . I checked the tube and found it to be clean so it doesn't seem like dirt was getting past the filter. I talked to a buddy that is a mechanic and he told me not to worry about it and that Crysler motors are notorious for this and as long as it's not dirt, it would just burn off if any of it went thru the system. Made me feel a bit better!
