trying to figure out when, if ever, to replace the timing chain on above vehicle. The Shop Manual is pretty informative rE; 3 L engines, but it does not specify when to replace or even inspect the 3.3L. Currently I have no problems with the vehicle, but am concerned whether I can confidently take it on a long road trip with 88K miles on it.
Is it possible the timing chain (it is a chain, not a belt) NEVER goes bad? An oversight in the manual? Suggestions?
TIA
