    can anyone tell me the general consensus on the 4.0l engine and the timing chain? i have heard the to start avoiding the engine when it gets around 170k on it as at that point the timing chain may start to become an issue and that may be why so many are for sale around that mileage.

    then i heard that ford redesigned the timing chain parts later on the have more durability. so it this happened what year did this happen and then after this happened what mileage would one start to avoid? thanks
