I've come to the conclusion that it was neglected by the PO
4.0 Powertech (whatever that is)
Latest change was to Castrol GTX 10w30 and a Mopar filter
I'm 2.5 on maintenance
I'm the second owner of this Jeep and hope to have it for many more years. Previously dealer maintained and I plan on keeping it up. Its my wifes DD and it will remain stock. Purchased to replace a 98 ZJ with 200,750 miles on it, over 100k by me on a steady diet of Castrol dino oil.
No major issues yet....
04 4.7, just cracked 89K about 2 days ago
no major problems aside from a slow seeping between the front of the block and the oil pan, and a slow leak above the water pump.
I change the oil every 3000 miles with penzoil 5w-30, going to royal purple synthetic on my next change to get as much out of this big V8 as possible.
I would be a 3, i absolutely lose sleep on the slightest leaks and feel the need to spend my life savings on rebuilding even if it aint broke yet.

2004 Laredo 4.7
Bought with 130k, now at 170k and runs perfectly. I've had to replace the axle seals, oil/transmission pans, cv joints, etc. but nothing catastrophic so far. Hell I even still have the factory exhaust without a single leak! I'm also extremely anal about maintenance, and I run pennzoil platinum at 5k mile OCI.
2000 Limited 4.7L 2WD. Purchased 8/13, with 160K on it.
Before I continue, allow me disclose, this was purchased knowing it would need some TLC. That said:
Ground in driver's door conduit repaired.
Spark Plugs changed
Oil Pressure Sending unit changed
New rear brakes, plus rotors machined
Headlights polished back out
A/C repaired (suction hose dry-checked and leaking, replaced accumulator with hoses)
Dent removed from rear hatch
Fuel injectors cleaned
Throttle body cleaned
Crank sensor replaced
Battery terminals cleaned, and cabling inspected
Loose ground repaired
Door panel clips replaced
I still have yet to solve the random dying issue, and I have a problem with the Infinity Gold stereo system where the sound will cut out.....pretty much whenever it pleases. I suspect the BRN/WHT whire to the amp has a break in it somewhere, but that is a small issue that can be fixed when I get it running.
2000 Grand Cherokee Limited 2wd, 4.7L V8 - It's blazing fast, blue, and the heap of Jeep.
2002 Dodge Ram Quad Cab 2wd, 4.7L V8 - Hailstoned, windshield cracked, storm chasin' truck. But dependable.
