    both of our 4.0 have rod knock but 200k miles on both cant complain. and 200k on our one that got wrecked
    I think some noise on a higher mileage 4.0 is typical

    when i first start this it allmost sounds like a diesel .... then settles down to several tickings but runs like a champ and make no noise when reving at all .. all this is new i never owned a jeep so im conserned ...

    a 4.0 that is in your mountaineer is a v6 i believe and a jeep is a straight 6 there easily mistaken . 4.0 jeep 4.0 mountaineer
