Timing Chain

[BlueOtter728]

So i was just curious on my 2001 expedition 5.4 4x4 what is the timing chain change interval for this motor? or is there even a recommended interval? i like the dont fix it if it aint broke theory but with timing chains i prefer to catch them before a catastrophe happens. ( my truck has 262K and runs great)

Because it has tensioners, Ford says it is good for the life of the vehicle. They also say the same about the 'lubed for life' rear end gear and some other components.

We all know that it's complete BS though.

With 262,000 miles on the clock, I'm not sure that I would spend the money to replace it. What will surely happen is that you'll run in to a ton of 'may as well' items along the way that will add cost to the project.

If its not making noise that means the tensioners are working properly and I would leave it alone, if you divide to tackle it, I would do sprockets, tensioners all gaskets and seals plus water pump

alright thanks for the input everyone. Wasnt sure really i just came from owning an interferance motor and havent dealt with too many OHC v8 last ford i owned had the 460 and after that was chevy small blocks and 4 cylinders lol. Thinking timing chain will just stay as is until i get a lower mileage or rebuild another engine for it.
