With all the oil changes my engine gets and as often as I get on the gas, I doubt my engine will sludge.
Whenever I used to take apart one of my Ford 302's the thing would be sparkling! Those things never sludged for me and no carbon either.
But for people who just crack the throttle and stay at LOW RPM's on a daily basis, that's a diff story.

Yeah...maintenance is the key.Most people do not
realize that high tech overhead cam engines require careful oil maintenance,maybe because these were seldom used in trucks and suvs. Daimler-Chrysler lease programs bring many of these low to mid milage vehicles to the used auto
marketplace,and care and maintenance is poor to non-existant.They(the lessee) just put gas in them.It is disgusting.Buy new if you can afford it,and if you buy used check it out completly.

You would be what?? Ten? Pedal your bic home.
Sludge is created by burnt oil and dirt from the outside. Proper maintenance would eleminate it in any case. The 4.7 is a high rpm motor for a truck motor with close tolerances. Take care of it and it will talke care of you. Quit blaming motors for your own faults. It should also be noted that there is little difference between the outputs of the 4.7 Dodge, 4.7 Toyota, 4.6 Ford and 4.8 GM motors. Stock they're almost identical in torque and capability. The 4.7 Dakota is a very versitile mid-sized truck that outperforms all the small trucks and competes very well with the bigger 1/2 tons. Nothing else is like it, so everyone else whines. The highest form of flattery. A new R/T with the 5.7 would be a blast though....

Deerridge - "DUH IDIOTS" only acts like he is ten; actually he is in his twenties - also posts as "NEO", "THE GOD" and many other assumed names. Probably a closet queen, he lives in Utah; and carries on conversations with himself using different names in these threads. Many of his postings have something to do with homosexuality, he can't seem to get off that topic. He has recently expanded over to dakotausa.com; complaining there how bad this site is while it is he who is really a big part of the problem. They caught him using multiple identities over there and warned him. I recently bagged him making off color remarks and posting under my name in a thread here and reported it to Mark, who had the thread cleaned up about 5 minutes later! Great work Mark, now how about banning this guy who mainly seems to detract from this site ? Pete- I don't think there is anything about an overhead cam engine that requires more careful oil maintenance, all motors benefit from good maintenance. There are many overhead cam motors in small cars still going strong despite poor maintenance. The larger 4.7 should do just fine in our trucks & suvs.

the 4.7 head does not cool properly in the middle at the bottom of the valve cover gasket and the oil cooks there and maybe other places also. this cooking causes sludge to be build and stop up the oil intake in the pan which causes the oil pressure to fall and if the engine is not shut off within a couple of secounds serious engine damage will be done. the cam bearings in the head are aluminum and just a very short time of no oil will cause damage. this is complicated by the bearing journals are only 1" with bolt on caps which weakens the bearings more.
ALL IN ALLL THE ENGINEER THAT DESIGNED THIS SHOULD GIVE BACK HIS PAY FOR ENGINEERING THIS ONE.
I HAVE SEEN BETTER ENGINEERING IN THE SOAP BOX DERBY.

I LOVED MY DODGE WHEN I FIRST BOUGHT IT. I DRIVE FOR A LIVING AND PUT ABOUT 75,000 MILES A YEAR. I CHANGED MY OIL EVERY 3,000 MILES DID ALL SCUELED MAINTINANCE.AND I KEEP MY FOOT IN IT AND DRIVE ALL HIWAY MILES. AND HAVE HAD A PROBLEM SIENCE 63,000 MILES. THANKS TO CHANGING MY OIL FREQUENTLY I KEPT MOST OF THE SLUDGE OUT OF MY MOTOR OR SO I THOUGHT. BECAUSE JUST LAST WEEK I WAS DRIVING ALONG AND MY OIL PRESSURE DROPPED CHECK GUAGES LIGHT COME ON ENGINE LIGHT BEGAN TO FLASH AND MOTOR STARTED SPUTTERING. I IMMEDIATLY SHUT OFF THE MOTOR AND HAD IT TOWED HOME. UPON FUTHER INVESTIGATION I FOUND THAT DUE TO SLUDGE BUILD UP IN MY HEADS THAT MY CAM HAD BROKE LOSE FROM THE HEAD BECAUSE SLUDGE HAD PLUGED MY LUBE LINES. UPON FUTHER INVESTIGATION I FOUND THAT DODGE KNOWS ABOUT THIS PROBLEM AND SENT A NEWS BULITON OUT TO DODGE SURVICE CENTERS STATING THAT DUE TO INSUFICENT COOLING IN THE UPPER REGIONS OF THE MAGNUM MOTORS OIL OVER HEATS AND COOKS FORMING SLUDGE AND EVENTUALLY LEADING TO COMPLETE MOTOR REPLACEMENT EVEN WITH SUFICENT OIL CHANGES.
SO YOU ASK ME WHAT I THINK OF THE DODGE 4.7L MOTOR WELL I THINK IT IS LIKE ALL THE OTHER DODGE MAGNUM MOTORS BUILT FROM 2000 TO PRESENT
THEY SUCK WORST MOTOR DESIGN EVER!!!!!!!!!!!!!
I WOULD RATHER SLAM MY WENIE IN A SLIDING GLASS DOOR THAT BUY ANOUTHER DODGE AND IF YOU OWN ONE YOU WILL SOON KNOW WHAT I MEAN!!!!!!!!! IF YOU DONT ALREADY!!!!!

So whats the solution for the sludge? Should we have our mechanics take off the valve covers and clean everything? Should we got to the dealerships and have them take a look?

A good synthetic, like Mobil 1, prevent sludging. Sure, it costs 4 times more but it won't burn up and lasts longer (5k-10k miles between oil changes). I use it in all my cars ('02 Acura RSX 2.0L, '73 Charger 400, '03 Dakota 4.7L) and never seen even the remotest signs of sludging.
Also, are you guys using the right grade? The owner manual says to use only 5w-30 in the 4.7L, like most modern engines.

Most Ford lovers, are a lost cause! They waste precious oxygen. The one and only good thing that ever came out of ford was the style of the 80's F-150, ya have to admit that is a pretty truck, and the 5.0 litre is a great engine, pretty much in the same category as the GM 283 and Mopar 318 for durability, economy, and power.
The problem with the Ford lovers, not owners, is that they are sniviling idiots, inclined to masturbating to thier own reflection in the mirror, they discount reason and logic to adopt the ways of brain-dead sloths. The good thing about Ford owners is that we can look at them and realize how fortunate we are to have the ability to reason logicaly, and almost feel pity that they are lifeless limps of the same substance that runs down their legs as they stand in front of the mirror with inadaquacy in hand. Give me your arrogant, your ignorant, self-wallowing, diarreah spewing and worthless. Give me your Ford lovers.

I currently have a Ram QuadCab 1500 w/4.7 & its doing me a good job--I got it used with 10,ooo on it but then again I saved 10 Grand on it too. I had for almost 20 Yrs a Ford F250 w-300-6 4 speed positrac rearend & limited slip frontend here in West Virginia & it used more gas than it should've but other than that I can't complain. It wasn't a hotrod but it took me ANYWHERE I needed to go & a heck of alot of places I shouldn't have been. Still had the original clutch & no engine parts other than plugs-wires belts & water pump--almost 20 yrs! I gave it TLC & good maintenance. AS long as it wasn't highcentered you went---period! I plan on giveing my Dodge TLC & maintenance as well--although its a 1500 series & not a 3/4ton & not as high as my F250 was it will still do me a good job hunting & fishin & allround. I guess time will tell--I know 1 thing I definitely get better gas mileage with the 4.7 over the 300-6 even if it does have a 3.92 ratio driveline--I can stay in OD alot here in WVa usually anywhere over about 35mph unless on a steep hill. It has a 5 speed.

I see it as rather strange for so many people to actually think that this engine is so sludge-prone. I am a master certified tech at a full line chrysler dealer and have only seen one 4.7L with an oil sludge problem. It was a fleet vehicle for a cable company and had NEVER had an oil change in 33,000 miles!! The driver claimed he just didn't have the time and forgot about it. In our harsh climate (northern minnesota) temp varies from 90+ in the summer to -35 in the winter, you would think that if an engine were to sludge up, it would do it here! But we only occasionally see this problem and it is almost always with the 2.7L v-6 with poor maint. So yes the 4.7L IS a good engine. I work on these cars, I see the failures and I have owned 3 dakotas with very few problems. The latest is an 02 with a 4.7L.

So i've come to the conclusion that the 4.7L is a good motor.
BUT the front end components are garbage. Total freakin garbage. I'm having my front brakes replaced for the second and final time (SSBC front kit) and my wheel hub assemblies are blown out. My tie rods are shot too. This is all with 50K miles on it. But then again it is a 2000 model.
Any how $760 ain't that bad. Its could be worse. I'm also haveing a radiator flush, a new serpentine belt, and five new tires/rims mounted and balanced and aligned.
DC just needs to quit skimping on parts to save a buck.

I have a 2002 Dakota sport 4x4 with the 4.7. In the last couple months, it takes 3-4 seconds to build oil pressure when starting. During this time, the CHECK GUAGES light comes on and 'dings'. Then, the oil pressure builds normally and the light goes off. I am VERY near the end of my 36k warranty and am wondering if I am in the first stages of oil pump failure due to sludge. I have been reading about it online and there seems to be several hundred (or thousands) cases. I change oil and filter every 3k miles and I use 10W-30. I have an appointment for the dealer to check it out this week. I've read so many horror stories lately, just wondering if anyone had any suggestions?
Thanks -

The 4.7 has NO major design flaws but is going to be one
expensive engine to overhaul due to the overhead cam design of
the engine.
So I recommend that anyone who owns one of these engines to
consider using synthetic oils ( Amsoil is you best bet ) due to
their superior performance compared to petroleum oils.

Another reason the engine will be expensive o rebuild is the lack of aftermarket rods and pistons. Right now the only way to replace a piston is to have one made or buy the piston and rod as an assembly. Also, there are no over sized piston/rod assemblies available even from DC. Therefore, if your cylinders require boring out you are S.O.L. because there are no pistons available in over sizes yet!
