Life of a 4.7 V8
#16
If you must buy a WJ
Get the 4.0 they get 250k with bare minimum maintenance, will tow up to 5k with no problem, just turn od off as you should anyways.. Never tow with of on
If possible get a zj with the 5.2 v8 low mileage ones are still out there, they made millions

I have a 2000 Dodge Durango with the 1st generation 4.7L. I have all maint. documents as it was a ChryCo Corprate vehicle. At 93K miles, I had to have the heads redone.....blown gasket between cylinders 1 & 3. Almost had to replace the heads to the tune of over $1800 just for the heads, the machine shop was JUST able to machine them within specs. Since then, I have had to replace EVERY SINGLE sensor on that motor; to include the power steering pressure sensor....really?!?! It has a valve tick, I guess the OHC motors from Dodge have a history of lash adjusters collapsing and causing valve train issues. Also, the rocker arms "jump off" and cause problems with the valve train. Its can be hard to start at times...I know, its a Dodge....... In my honest opinion, Id stay way clear of Dodges one and ONLY OHC V8. Theres a reason the Hemis are pushrod motors. Ill never buy another 4.7L powered Chrysler product. A buddy of mine had a 1999 Grand with the 1st gen 4.7L. At 73K, the oil pump quit and it threw a rod through the side of the block. Ruined the block and broke the bed plate in 3 places to include the crank journal.

The dodge 4.7 is a different motor from the 4.7 jeep. Retarded but then again Chrysler...... yea. But anyways the jeep 4.7 is an alright motor the 4.7ho has different heads and cam and is tuned very well. Its hit ot miss on a good one really cause it seems to me that jeep motors are meant to be ran hard and not babied. Idk why but thata what ive seen. Just my .02

I beat the ***** off my 4.7ho... its not happy anymore. I'm so not impressed with the 4.7 at all! I got it with 32k, and i'm just hitting 78... I wish I never got the thing. And cause I can't be bothered with fixing the head gasket, I just burp it once a week lol. I don't even care about it anymore. Awful Awful motor!

Her choice of the WJ is wise, I believe. There are so many other look-alike SUVs out there you have to see the grill or read the badges to know it's a Jeep! It is stylish and contemporary. Hell, the Mercedes even looks similar.
That is because Mercedes owned jeep from 99 to like 04.

Perfect timing, I'm looking at buying one of two '02 WJs. One has the 4.7HO w/169,000 miles and the other is standard 4.7 w/147,000 miles but 15,000 on the rebuilt engine. Both have quadradrive, tow package and all the other bells and whistles. Can't wait until more of you guys chime in, I'm not swayed either way yet.

It's going to come down to personal prefrence. I own a 02 WJ Overland with the 4.7 HO. I have maintained it well from the day I got it. It has been and still is a awesome vehicle. No problems. I own a XJ and a TJ with the 4.0 HO. Great motors, no problems with them either. Please don't tell me the 4.0 will tow as good as the 4.7 because I have first hand experince and it is not true.

The only reason for the 4.7 H. O. Is because Chrysler couldn't keep up with the demand for the 5.7 hemi, could you imagine a solid axle 5.7 hemi rig?

Wrong again. The heads are the same. The intake manifold is different. Same cams. Possibly slightly retuned PCM...Ill have to look into that. The 1st gen ('99-'00) 4.7s had 16 tooth reluctor ring for the crankshaft position. The 2nd gen ('01 to present) have 32 tooth rings, allowing for better timing and slightly better performance gains, along with the reworked "HO" intake and PCM programming (maybe). Either way, the motor is nothing more than a boat anchor and the 4.7L is FINALLY going away.....If I could afford a 5.7L swap into my Durango, I would and sell the 4.7L off for scrap.
