Jamesj250 I have the 2.5 with 140,000 miles and runs fine with no problems, just a gear issue.

bigjohnjeep MY '97 had a 4 banger and it ran like a sewing machine. Really. It was just under powered. I cannot complain at all about the reliablilty. It had 180k on the odo when I traded it.

Try again... 4cyl on 35's vs 6cyl on 31's Not the same thing. If you want to make a comp then slap some 35's on your 6 and see how well it gets up to speed since that seems to be what you base how good the 4 vs 6 is...

Loic when i bought my 98, engine was bad the jeep had arround 125k miles. lack of maintenance is most likely the culpid, when i drained the oil it was more fluid than water if thats possible.....

We did not tear down the failed engine to diagnose the root cause.

An original Chrysler/Jeep engine was not in stock and was no longer available in Maryland at the time.

My son was eager to get back on the road so I bought a Jasper remanufactured engine that came with a warranty.

I had to weigh the total cost, labor, time, and inconvenience to rebuilding the original or going with the remanufacture replacement.

I really wanted to try a diesel conversion but haven't found a qualified shop yet.

Fatbob309 I have had 3 4.0's and a 2.5... The 2.5 is a good little eng. Like I said before not a power house at all and you will need to gear the snot out of it to run bigger tires but over all I would drive one again.

10-08-2009 10:38 AM

the old 2.5 did not have a belt, the new minivan 2.4 built on the neon motor platform has the belt.

i'd put my money on the fact that no one changed the oil on the motors that go. both motors will last forever if mantained.

kdukes4 mines at 118k and i love it! might not have the ump like the 6 but she kicks it into gear when she wants. and off road wise handles exceptional too. plus, if you're not looking to regear soon, you start with 4.10 gearing, so throw on some 31s if they're not already on. most peeps on here wont admit it, but even with their 4 liters, when you're sitting on 3.07 gears with anything greater than 33's. we'll they'd prob wish they were sitting in your shoes instead.

Jesse-James How many of those ads can provide paperwork for the rebuild. Many CL ads are full of shit.
10-07-2009 09:44 PM
Jeepzcb09 look at craigs list and every 4 cyl say "rebiult motor" or new motor" and then look to see how many miles are on the body, and for example most of them say around 100,000 miles(give or take a little) so that means the motor blew around 100,000 miles!!! Sounds pretty shity to me.
10-07-2009 06:41 PM
jdhallissey Got one now with the 5.13 gears it moves ok and gas is not to bad. I think I picked up some mileage with them.
10-07-2009 06:36 PM
Fatbob309 I had one that outlasted 3 jeeps it was in. It was a great little eng. Not the fastest kid on the block but I got great mpg running 37's and 4:88's with the 5spd.
10-07-2009 05:05 PM
