AdroitKirby Posted September 24, 2022 Share Posted September 24, 2022 Got to 217k before I had the engine rebuilt due to a rod bearing going out. I was getting 7 mpg at that point, but the truck still ran. Used the engine tech full rebuild kit. It's at like 220-225k now Link to comment Share on other sites More sharing options...
XRT38 Posted December 8, 2022 Share Posted December 8, 2022 1990 2 wheel drive long bed. I had the motor rebuilt at 360 thousand miles about 12 years ago. It's the same original motor but they had to bore it 60 thousands over to take the oval out of the cylinder tubes. I have to guess but I think it must have at least 500K on the motor. I bought it new 32 years ago this January. It was on sale for $9,999 at the time. I'm 66 years old now. We both look well used. Link to comment Share on other sites More sharing options...

Clay Perrine Posted February 4, 2023 Share Posted February 4, 2023 1988 2wd Pioneer. Original 4.0 Engine and auto transmission. Valve cover and oil pan have never been off of the motor. 298,900 miles. The motor is very tired and needs rebulit, but I was trying to make 300K before I do it. My father bought it new. I drove him to the dealer to pick it up in 1988. He used it to pull a car trailer with vintage Chevys on it for years. Now it's mine. Only mods was to replace the instrument cluster after the speedometer shelled itself with one from a Cherokee that had a tach, and the radio was replaced. But I still have the original radio a box on the shelf. This is the most current picture I have. It's in the garage this morning to get brakes done.

coheed Posted August 9, 2023 Share Posted August 9, 2023 Never posted mine in here. 324k on the odo when I bought it, and I've put another 18k on it since then. However the cable was unhooked, so who knows. Doesn't have the telltale red tag that the replacement 60° V6s had, so seems to be original. Link to comment Share on other sites More sharing options...
AnotherOldJeepGuy Posted August 10, 2023 Share Posted August 10, 2023 I looked around for a poll but didn't find it, or perhaps that's something I don't know now to do. Regardless, my 1990 has 220,730 and runs great. Link to comment Share on other sites More sharing options...

AnotherOldJeepGuy Posted August 11, 2023 Share Posted August 11, 2023 I see a graph, but nothing that looks like a poll input to this newbie. But if you can point it out on the pic attached I will gladly add to it! Link to comment Share on other sites More sharing options...
Pete M Posted August 11, 2023 Author Share Posted August 11, 2023 it would appear you did vote on April 22nd. clicking here, I see your name at the bottom. Link to comment Share on other sites More sharing options...
AnotherOldJeepGuy Posted August 12, 2023 Share Posted August 12, 2023 Hmm, well I have obviously slept since then. Maybe that's why I don't see any way to vote now, maybe the polling tool is too smart to let someone vote twice! Just to continue the fun conversation, I can't see my name by clicking where you said, that's not clickable for a mere user I guess, only superusers!

FrankTheDog Posted August 22, 2023 Share Posted August 22, 2023 Not a Comanche but still a 4.0 HO. 1998 XJ bought it in 2007 with 209k on it from original owner. At that point the engine had never been touched internally. I drove it to 453k in 2018 when I finally parked it. It still had never been opened up. Original valve cover and oil pan gaskets. It still ran halfway decently but the XJ was basically driven into the ground by then. No picture of 453k but here is one from 433k. It was my most favorite vehicle ever. We went on many adventures.
