I'm contemplating buying a 2005 Dakota that comes with a 4.7 magnum. I'm fairly well educated on 5.2 and 5.9 magnums, but this is a new one for me. Any feedback on this engine, good - bad - or indifferent?
Feedback on 4.7L V-8?

The only thing I've ever heard about them is straight out of the mouth of a Jasper Engines rep. He was telling us about how they used revised oil pump pickups that were larger and flowed more oil to help combat cooked oil in the pickup tube. He said they had seen a LOT of cores with either very restricted pickup tubes or completely stopped up tubes and that was their fix for it. Other than that, I have no experience.

From what I heard they're good engines, just have to keep up on oil changes. I guess the oil system is too easy to clog up or something. Might just be the pickup tube mentioned above.

I drove a 2000 Durango with the 4.7 engine for about 8 years. Body rotted out because of salted Pennsylvania roads but the engine never gave me a bit of trouble. It had plenty of power and I even pulled a 6x10 utility trailer with 2 Harleys on it to NC and back. It was AWD so gas mileage sucked. I ended up selling it with around 120,000 miles.

Doesn't this kind of go against the whole getting rid of stuff?I'm not buying anything?????????......
At least that's the way I remember it, where i'm getting really old here, and I can't remember very well....
I had a 2002 Dodge 1500 with that engine. I sold it in 2006 with 163,000 miles on it.
Zero problems with the engine, trans, axle or brakes. The dealer replaced a leaky steering rack under warranty.
It looked near new when I sold it. Not a powerhouse but a great truck overall. I followed a 5000 mile interval regimen.

Looking at selling the two I have and downsizing to a mid-size truck.
I put 228,000 on mine. changed oil every 3k. I really like it and it had plenty of power to pull my18 ft trailer.
I have our 2000 Dakota with the 4.7 and love it. Wife loves it for errands on our small farm. Valve covers never seem to seal right even after new gaskets.
Ours has 167,000 and I race to fire calls in it. Almost daily, towed well also. I wish I could turn back time and buy another brand new. SN: ac is always an issue but not a 4.7 issue but a chrysler design flaw. The ac evaporator in the dash is an 8hr job to replace as they rot out.
It will be cold again and the ac will not matter again. lol!

Gf jus5 passed 100k on her 2006 Dakota with a 4.7. No complaints, other than needing a trans overhaul. Maintenance done regularly by her sisters auto shop.
I love the way the exhaust sounds too. Quiet, but growly.
A/c works good, and it's a good thing! See 115 here frequently.

Rusty that happened to the first while whale, a 5.2. Dodge went to those God Damned "trumpet" oil pickups. the tube simply comes and bends straight down, and there's a small screened "trumpet" on the end. They plug up with sludge.
See post 4:
Regarding 4.7's, suddenly they are good?? I used to hear horror stories about them failing, dropping valves/ valve seats was one issue.
The joke used to be that Mopar, "anything dot 7 is junk." AKA 2.7, 3.7, 4.7, and even a few of the 5.7's

I have a 2000 Dakota with the 4.7 & have had no issues. It's pretty low milage, but I like it. If it was serviced regularly & not run hot, they are good engines. Check out a guy that's on YouTube called Martin Built, he knows a lot about these engines & even mods to do to them to get more horsepower. He can tell you the in's & outs of these engines. Lot of good info to use. It's a more modern engine that the 5.2-5.9s, & some things are more difficult to do but, they are a pretty stout little engine if taken care of.
Lifters are the biggest issue but easy to change by just pulling the valve covers.
I’ve heard of the oil pickup plugging issue. Was once told if they make it past 50K miles, you got a good one. Dad had one in a Jeep that ran well for past 100K miles and had a buddy with one in a Ram that he ran well past 100K miles and was still going strong

I've got an 04 Dakota Quad cab that I bought out of a repo yard with a blowed up 4.7 in it. I bought a reman 4.7 from Powertrain Engines and put in it. I haven't had any trouble out of it and have put 50K miles on it since I've had it. I change the oil every 3500 miles and it doesn't burn or leak a drop. If you let a 4.7 overheat, they are done....so beware of that.
I had a 2004 Dodge 1500 with that engine. I bought it with 83k miles and sold it with 150k miles. It was a great truck with no problems. The only problem was that I f**ed up and didn't change the oil in a while, so it sludged up and busted the plastic timing chain guides. Then it skipped time and I sold it... It was a great truck though..
I bought my 2004 in 2014 SLT 4.7 club cab. I keep the oil changed and the maintenance up pretty well. It had 43,000 miles on it when I bought it it now has 124.000. it purrs like a kitten it has been a very good little truck. The only problems I've had is both exhaust manifolds cracked. The wiring that comes out of the fan junction gets hot. And the headliner is now sagging. I feel those motors do better and cooler climate and in a very hot ambient temperature may contributes to their oil gummin problems. I've never seen any sign of that in my motor here in Oregon.

My friend over there in hazeldale has one of those four sevens in his truck and pulls the snowmobile trailers and everything.And they're well known to be three hundred thousand mile motors, as well as the 5.2.And the 5.9....
I don't think any one of the three would set your world on fire as far as better gas mileage than your slant six truck... ten times easier to get parts for the pick and pulls are full of those trucks.And of course, the durangos, as well crossover as far as the whole front clip and doors...
I i've never heard of anybody who didn't like the 98-02 durangos and dakotas...

Big blocks rule small blocks drool!
I had a 05 Ram that had a 4.7 with 35k when I bought it and 55k when I traded for an Expedition was 34 k and twelve years later I still have it but now has 145k.
I traded the Ram for one reason and that is the 4.7, piston slap the 4.7 had and because of the terrible reputation the 4.7 has…
I would recommend staying away from the 4.7 and looking for a 318.

Ive got an 05 Dakota with a 4.7 now - trans just lost 3rd gear but the 4.7 is still good at 155K. I had an 01 Grand Cherokee that had 288K on it when I sold it and it was still running great. That said - 4.7's get lousy mileage Both my full size 5.7 trucks got better mpg with 50% more power to boot.
seen them drop valves done head gaskets and timing chains
easy to work-on always thought they where good ,but the 5.7 is worlds better
i've had every gen of dakota ,all had 6cyls none ever gave me engine troubles ...none ever had power
