Life expectancy of the 4.0
what the life span of 4.0? does it get up to a certain amount of miles before known things need to be replaced/rebuilt, i found a 94 wrangler with one for 1500 bucks, so i figure i could buy it for the motor and tranny, and piece out the rest... but it says high miles.. so is like over 150K considerd junk and how much would it be to rebuild it..i could use the 4.2L block right if i wanted to replace it, and use the head and everything else to fit,? thanks!
