I checked out the dakota forums and read many threads indicating that this was common at least for the early 4.7L's due to condensation from different cooling rates of the block and the location of the filler tube. I tried replacing my pcv valve and was almost ready to tear into the intake manifold gasket before i found that on the dakota forum. I have noticed it in mine since about 90K (i bough the truck with 80 K and didnt drive much the first winter). I just clean out the orange sludge as good as i can with every oil change.

edit: I only seem to notice it in the winter
You hit it on the head- oil pulls the moisture that condensates naturally in the engine, it evaporates out as steam & normally rises to a high point in the engine = the fill tube. the fill tube is plastic & doesn't heat up like the engine block. The slime layer that builds up in that fill tube is very common in several chrysler products, the 4.7 being one of them. From what I have read & discussed with a few people, who I consider educated on the subject, it seems it's not such a big deal. Be careful when you clean it out that you don't knock more of it down in there than you get out. If it does get in the system the heat will just disolve it & start the process over again.

Short drives &/or less vehicle warm up seem to make it show up faster than those that are driven long distances, or in warmer climates. This may be why you notice it in the winter more.

Mine has this similar problem. It does not look near that bad in that oil cap. I originally thought a blown head gasket, but I never have to put coolant and the oil is not milky when I drain it. I too noticed it's only during winter time. I take it from these past posts, that this is normal. Sure takes a load off my back.

don't you let your car "warm up" before driving it? especially in the winter it's not good to just get in and go...

I dont let it warm up... I let it sit for like 30 seconds. It would take 30 minutes idling to heat that thing up!
