Anyone brake 300k on their 4.0?

 

Few have... many have come close. 300+ is possible and I have heard and read about 400+.

 

while I didn't put the miles on it, my '91 has 321k. Not running right now, needs a fuel pump. She still looks good too. Coach

 

On my jeep it only reads about 240k, but at somepoint before i got it they swaped the motor for a HO straight 6, so i have no idea whats on it lol

 

yes my 92 cherokee has 304995.5 miles on it run great still. Only owned it for 5 months plenty of power. When weather breaks will start to tear it down and get a look at the inside engine but dont anticipate any major problems.

 

all 4 of mine have gone over 300k. the one i have right now is at 326k and works great, no leaks or burning oil

 

no leaks, oil. it was fixed at some point.

 

I got about 286K, so Im getting close and its still running strong

 

1989 stock Laredo 267,000. Runs great no oil consumption. A little rough idle, the previous owner messed with some vaccuum lines.

 

mine has some blowby, but its due to the previous owner who really neglected the poor xj. when I first got it, I pulled the valve cover, and it looked like the head was storing molasses

 

My '91 has 67k right now. So it's good to see, I have about 230K to go. And I'm planning on doing so!

 

WOW 67K on a 91, that is amazing, was it always garaged?

 

I inherited it from mother in Nov. 2008. (Had 64k when I got it.) It was her grocery getter, so she didn't drive it much. A tank of gas would last her almost a year. There's pics in my photo album. And that's why I haven't modded it yet. But I do plan on keeping it forever.

 

It looks incredible, like right off the dealership lot. Im jealous bub, my Jeep looks like I saved it from the junkyard, hahaha

 

Yep well over 300+ I have an oil leak I cant get to stop unless I do Rings and such, but theres no way, I still have major compression and so on. So I built a oil recovery system for wear it leaks.
