Pete M Posted April 14, 2019 Posted April 14, 2019 partly playing with the poll feature, partly looking for a graph showing how the stock engines are doing. multiple choice answering is allowed for guys owning more than one. If your trucks both have 175k, then I don't know how to accommodate that
Eagle Posted April 14, 2019 Posted April 14, 2019 You said "trucks," so I didn't include my original '88 Cherokee. 287,000 miles and still running (when I get around to replacing the leaking injectors).
gogmorgo Posted April 14, 2019 Posted April 14, 2019 Well 498,400km on the first 4.0 in my first MJ before I pulled it puts me in the 300+ club, by just. I also added one for the ~270,000km that are now on the engine that replaced it (240,000 of which were accumulated by the XJ it came out of). I've also got 172,000km on the other MJ's original 2.5 when it came out, but it's death was due to neglect from the previous owner. Sometimes when your crusty old radiator is leaking, the fact it quit leaking on you doesn't have much to do with the stop-leak you were pouring in the top as quickly as the coolant was coming out, and more to do with there only being a finite amount of coolant in the system...
Dzimm Posted April 15, 2019 Posted April 15, 2019 Didn't realize you could select more than one. I also have a unknown mileage engine swap truck.
mjeff87 Posted April 15, 2019 Posted April 15, 2019 The original 2.5 in mine had 200K when I swapped it out for the 4.0. It then got swapped into another MJ and ran for about 2 years (don't know how many miles in that time though) and finally met it's demise when the block froze and cracked from sitting out in the winter with plain water in the coolant system..RIP The 4.0 I swapped in had almost 200K on it, I just freshened up the top end (nothing on the bottom end was touched, except for a new oil pan gasket lol). I drove it for several years, probably putting another 30-40K on it, before selling it off. I have no idea what happened to it after that. The new owner seemed like a cool guy/wrench head, so I assume it's still running somewhere out in the hills of southern VA. At least I like to think it is. I check Craigslist every once in awhile to see if it ever pops up.
FrankTheDog Posted April 15, 2019 Posted April 15, 2019 Not an MJ but my 98 XJ has 457,000 miles on it. The internals have never been touched. It runs so well I’m thinking about putting it in my YJ build just to see how long it keeps running. It’s to bad that the XJ is extremely rotten. Much worse than this picture shows.
Minuit Posted April 15, 2019 Posted April 15, 2019 My '91 is still running great at 177k. My '89 has approximately 140k and is in no way running great. Change your oil (and don't let it run out) folks.
87MJTIM Posted April 16, 2019 Posted April 16, 2019 Mine has 301k miles. It did get "refresh" rebuild at ~267k. Still the original block, head, and crank - not sure about the rods and pistons.
Sleezak Posted April 20, 2019 Posted April 20, 2019 120,000. Basically brand new! Runs great for being 29 years old and sitting for lord knows how long.
RustyRodder Posted April 20, 2019 Posted April 20, 2019 224,xxx on my 88 4.0. Original as far as I know- needed a new oil pump, and has a case of disappearing coolant (really hoping its escaping the pressure bottle).
buxmj Posted April 22, 2019 Posted April 22, 2019 Just turned over 264k today, still running great! Buck.
Manche757 Posted May 30, 2019 Posted May 30, 2019 Is Dvitha still around? He could win the mileage contest - 672,000 - on one of his MJs back when.
bigmistake Posted May 31, 2019 Posted May 31, 2019 I'm about to break into the 200k club (okay, not as cool as the 300k+ club... but the most I've ever had on a vehicle).

Vineyard86manch Posted July 24, 2019 Posted July 24, 2019 I hope I can reach the 200 or 300k club, this truck will be at least 50 by then. Just hit 60k yesterday

Vineyard86manch Posted July 24, 2019 Posted July 24, 2019 This island is about 20 miles wide so yes it might take awhile:) The funny thing is I bought it last March with just under 55k on it so it’s actually been driven more on the island in the past year than it had per year when it lived in Northern Montana!
schardein Posted July 26, 2019 Posted July 26, 2019 2001 Silverado 310,000 (original 6.0) 1991 XJ 238,000 (pretty sure the 4.0 is original, and runs strong) 1991 MJ 159,000 pretty sure it's the original engine, it as a weird piston clatter sound on cold start ups. Definitely doesn't run as strong as the XJ. I have an unknown mileage 1996 4.0 long block I will be swapping in. My CJ-7 has 242,000 miles but is on it's 3rd engine, original 258, swapped 4.0ho, swapped 5.3 I used to own a 1989 XJ Wagoneer that went to just over 300,000 miles before I sold it.
