Interesting observation. I'll definitely listen for that.

nothing to worry about just oil returning to the bottom of the engine, probably more audible due to the vast amounts of oil in the 4.0

Mine does it too, but if you pat close attention it sounds to light to be oil so I figured it was coolant.

If you squeeze your large hose going to the water pump slightly it sounds the same. (on mine anyways)

I thought it was coolant as well and made sure there wasn't air in the system. So when I shut the engine off I laid under the Jeep and could hear the oil drainging into the pan.

Wouldn't think one would hear coolant.....there's no place for it to drain back too.
