Check the o-ring or gasket on the oil fill cap, it either hard or missing allowing condesation to merge with the cooling oil vapors at the fill. this will give you that sludge also. Like stated above, rule out any loss of coolant with the simple coolant system pressure tester. these can be rented at your local auto parts store.
 
coolant is in the normal range its got a type of dipstick in the overflow tank and its at the full mark

ok ill have to do a pressure test ill also check out that oring.

i have always thought that if coolant was getting into the oil that it would settle to the bottom of the pan due to oil floating on water (cant seem to remember what the term for that is! brain fart)
 
ok i was searching around on a dodge forum and it seems that it is nothing to be overly concerned with. i guess what happens is that the oil fill is in a bad location and condensation gets in there due to bad seal or pcv and emulsifies with the oil vapors. i guess this is a very common problem with the 4.7s in the dodges and jeeps thanks for the help guys
 
Yr correct, water is heavier then oil hydrocarbons most oil will float on water.

My 96 GM 3.1 V6 blew the intake valley gasket at 46K and filled the crankcase will the entire contents of the radiator. It was most obvious with mine it pegged the temp gauge and I shut it down when it stopped blowing heat from the defroster. Saved the motor, resealed the intake flushed out the crank & it's been running ever since, now at close to 180K, who would of thunk it.

That condensation build up can also be from short trips in cold weather & lack of timely oil changes.
 
Josh, did you find the Durango Owners Club, www.durangoclub.com? I'm a long time member, have an '03 Durango R/T 5.9.

You found the right info, on the 4.7's that sludge accumulates around the fill tube, doesn't cause any problems at all. I had a 4.7 before my 5.9 and worried about it a bit until I read about it. If you want to clean it up get ready for an oil change, warm up the engine, and wash the crud down with motor flush or diesel fuel (with engine off) just before dropping the oil, should cut the sludge quickly and it will drain out with the oil.

Well ..... they've certainly had a few strange ones over the years. But, I'm a fan of Gen 1 Durango's. I liked my '01 4.7, the '03 5.9 is a lot of fun to drive, handles very well for a 5,000 lb. SUV. I've got a few basic mods on it, nothing major, but the 5.9 is an old style V8 with lots of torque. The Durango is kind of like a 6.5, there are a few items to fix, few things you need to know, and once you get past those glitches they are very good vehicles. Around here in the northeast its amazing how many you see on the road, and the Gen 1 design ended in '03.

Actually this one was a POWERTECH design, AKA MERCEDES. The 4.7L came out right after the merger and was a MERCEDES engine slightly redesigned for a truck. Alot of people get that build-up for some reason, I never had it with mine and never seen it much when I was working for DODGE. The 4.7L is a great engine, but doesn't take any kinds of neglect very well at all.
 
my 88 ranger 2.8l does the same thing- hard o-ring. had the same puzzeled question about it. puuled the pan and no water just clean engine parts, but the oil fill on the cover was just nasty.
 
I know what a 5.9L is ....... and I had a 97 Dakota with a 318 and a 5spd..... kept blowing CV axles........ I am not going to knock the Mopar push rod engines....... even the 3.8L V6 in the wife's Town and Country (may it rot in hell) was a bullet proof engine ...... And they had some good Ideas ....... but they lacked the engineering to make their good Ideas work and refuse to own up to their mistakes .......... 6 times before I had 20,000 miles on my Dakota it was in for a new timing chain.... I finally replaced it with a double roller before the TSB came out....... backed over some clump grass and pulled the front bumper right off ........ broken lug stud for absolutely no reason........ window switches would just quit working, the locks would ony work when they wanted to....... it was an expensive pile of crap compared to the 3.9L powered 89 Dakota I traded in on it.
After 2 1/2 years I finally traded it in for a 2000 Tacoma.... would still have it except I got married and when the lease was up we got (what I thought was) a sweet deal on the 99 Town and Country.





don't get me started on items that should have been recalled on the 97 - 2000 minivans........

The coolant would settle out eventually IF it sat for quite awhile. If you're checking it after running it, or even within a day or two, the coolant would be emulsified in the oil (i.e. milky oil).
