  • life of jeep engine?

    if a jeep has been taken care of how long does the stock motor specifically the 4cyl and 6cyl. usually last without major work like a rebuild?

    you will most likely get over 200k miles on a 6cyl im not sure about a 4cyl though

      198k,On mine and it blows blue smoke ...I think with proper
      maint(mine did not have) :mad:,the engine will last
      to 250-300+k easy.

          Well I had one BLOW up big time at 260K but I only had it for 20K miles I have a another one that has gone 180K so far with excelent maint. that seems to have a bad exhaust valve a third one with 150K no problems and the 4th has 88k with no problems so my estimate is

          260+180+150+88 / 4 169.5k on a 6 cyl with no problems. 2 of these have had unknown maint. and range from a 1960-1999 6 cyl.


          I guess 200k with good care seems resonable

            i got 220,000 from mine before it started getting loose. it still ran fine, but was getting sloppy, and wouldnt pass smog. replaced it with a 98' motor.

              Jugding from some of your photos, that 220,000 weren't easy miles

                well, thew truth is.. i have put like 10,000 miles on it since i got it. i have had it about a year, and it had very high miles when i bought it. it was owned by a 70 year old man that didnt trust it any more. hes wanted it out of his driveway, so i got it for a song. it was completely stock when i got it. i used it for 6+ mos. without having to do anything to it mechanically. when it came time to smog, it wouldnt pass. had loose, and tired valves, bearings, etc..
                so, rather than dealing with the delays of fixing it, i swapped it. it was waaay less expensive this way, and muuuch faster. it was down for 2 days for the swap.
                passed smog on the first try.
                since i have had the jeep, it has had some rough miles. before i got it... old man miles

                  Just came back from Camp Jeep seminar and the speaker/author mentioned that the 6 should easily see 200,000 to 250,000 miles provided you change the oil regularly. OEM Reman engines are rated for 200,000 miles.
