Sludge in Oil Refill Compartment
Have a 2001 Durango and when I went to add some oil, in the refill compartment was this colored sludge on the inside. What the hell is this and how do I fix it?!

RE: Sludge in Oil Refill Compartment
Engine? Miles? Refil compartment?
I hope you were talking about the valve cover.. If not that coolant/steering fluid/ or brake fluid is going to be nasty...
Why were you adding oil? Low on it?
Burning oil? Lacking on oil change? (maintenance)
Slugde cream colored?

DSM:
The cream colored stuff you found is called "emulsion" by Chrysler. It is known to be a common sight in the oil filler tube on the 4.7 motor. The explanation is that it occurrs because the filler tube is plastic, and does not warm up well from engine heat enough to prevent the condensation from forming. Usually, it only occurs during the winter months for those of uswho have them. Some say running synthetic oil will help prevent it, but have run Mobil 1 since I bought my D and still have it now and then. Plus, my round trip commute is 8 miles, so the engine does not get to warm when its cold out.

RE: Sludge in Oil Refill Compartment
This is an after the fact update on my first post regarding oil sludge in the filler cup. Too make a long story short. I ended up having a cracked block. The dealer took care of it under warranty.
There is a TSB referring to emulsion. I've seen it on mine after the repair and on other 4.7L engines. A little is normal (according to Chrysler) but a lot could be cause for concern.
If you have alot I suggest you get your oil tested. Mine test positive for Glycol.......................

RE: Sludge in Oil Refill Compartment
First, check to see if you are losing any coolant. If not, then you have the emulsion problem previously mentioned. Dodge has put out an update to this issue. I was having the same problem. There is a new designed oil fill cap and a plastic baffle that fits directly down the oil fill neck. That will take care of your problem. The cost for both the oil cap and baffle was around $20.00. Hope this helps>

RE: Sludge in Oil Refill Compartment
if your engine is a 4.7 they all get it even with the TSB just not a bad
dodge ram's
jeep cherokee
durango's
but for some reason only durango's sludge so bad the engine blows up which is a line of crock, there are probably over a million of the 4.7's out there very, very good engine
short trips will increase the white cream in the cap, but longer trips will burn it off
all engines do this in cold climates you just dont see it like we do cause on all other engines the oil fill in on the valve cover and not a plastic neck 6 inches higher than the engine, poor design to say the least
just make sure on your dipstick it is not white or creamy then you have some issues!!

IndyD is right.
I have personally seen 4.7L motors blow because of sludge. Synthetic is a lot better to run but you still can only go about 3000 miles max in the 4.7L. Condensation is the main contributor of this problem but I have seen other issues cause this problem including intake gaskets, heads gaskets and block cracks.
First make sure no other fluid is low. Compression checks can find a leaking head gaskets.

RE: Sludge in Oil Refill Compartment
maybe I should have not said it that way
a better way would be to say they point all the problems to the ooze in the oil filler cap, as a reason for failure in some cases yes but there are other problems to create it agree fully %100
agreed if losing fluid there is a issue and not finding it on the ground
