4.0L Jeep Engine

[ekcivic1991]

Anyone in here ever owned a jeep cherokee or any jeep with the 4.0l inline six? If so how many miles did you have own it and how did it run. Ive heard of them going over 200k strong but i dunno

I've heard the I6 is a really solid engine more so than other parts on the jeep. The only thing I've ever heard negative is they like to leak oil.

I remember my friend having one that had over 300k on it and it ran pretty strong, but also leaked oil but wasn't too bad. We used to go crazy in creeks and trails with it.

damn 300k
and im looking at one with 185,000 but i just had the rear main seal replaced. I just wasnt sure about how they were with high miles

Everybody gives cars with over 200k a stigma that they are complete shit after that. Yes they can be if they weren't maintained. It's ok to a have if you don't plan on selling it. I actually just talked to him a couple of minutes ago and he said that it crapped out around 34Xxxx. We put that thing through hell.

i had one but it only had 113000 on it and it ran perfect. my friend knew an old lady that had one and she took perfect care of it. had over 400K

My uncle has one with almost 300k on it now, it leaks a little oil, but it still runs good.

worked on to many to count. as long u the owners took care of them ie change oil. i havent had a single 1 with an internal problem.

My brother has a 1990 Cherokee 4.0L. Has close to 200,000 miles. Still runs strong

That old lady deserves some REPS lol

My 2wd cherokee has 289k miles and still runs like new, the only problem Ive had are with the driveshaft.

[ekcivic1991]

damn thanks for all the help

[Arm&hammer]

my old jeep had 180XXX and still ran great. I say go for it man.

It's definitely not an engine you have to worry about. Maintain it and watch your seals for oil leaks and it will go as long as you want. Mine blew up at 250k but I beat the living piss out of it constantly so it was understandable. I know several people who are at 300+ running strong with just basic maintenance.

i havent but my bro and sis have them both have the original motor and over 230k miles still running strong with no oil burning or smoke. the jeep 4.0 engine is built like a tank

I know you are talking about a 4.0, but I drove an inline 6 the other day and I got a little excited when it kicked the rear end out. Wasnt expecting to be drifting a Cherokee, lol.

[ekcivic1991]

repped all i could but sorry to the top i started from the bottom up

My dad has 2, a '89 and a '95, both 4x4. On the '89 it has a sealed cooling system, they have had some minor problems with, '95 hasn't had any though. One thing about the 4.0 cherokee is if the left motor mount goes out the exhaust manifold breaks, we replaced the mount and welded it back....pretty easy fix.( or you can buy the aftermarket manifold with the flex pipe in it for like $300) Other than that he loves them.

My daily is a 92 cherokee with the 4.0, almost 200k and no problems, I sold my last one with the same motor and it had over 240k and a co worker still drives it daily 80 miles round trip with no issues... Great Motors, i hear good things about them all the time...

[Tech5]

Mine has 358k miles with no issues BTW mine is a Police edition one and it runs pretty quick out ran a few integras, an civics
