95 Ford E250, Timing Chain Replacement
Q: I have a Ď95 Ford E250, with a 5.8 liter engine. Currently my van has 397,000 miles on it. It does not use any oil and it averages over 16 MPG at 80 miles per hour on the highway. I am concerned that having this many miles on my motor (it is the original motor) that I should replace the timing chain. I asked my local Ford dealer and they said to leave it be. I want to know your opinion, 397,000 miles is not a misprint.

A: Wow thatís a great question! Nearly 400k ! Clearly you do a lot of windshield time in this vehicle. You didnít say but it must be part of your livelihood and down time would be a problem unless itís planned time. I would recommend replacing the timing chain and gears at your mileage. But, I would recommend servicing other components as well. These components would include the water pump, coolant hoses, coolant, thermostat, etc. Why? Because you have to remove 90% of these parts just to service the timing chain. Youíll save money doing a complete job vs. going back into service these items at different times. Not all replacement parts are created equal. When replacing these parts "do not" use bargain basement components! There is a difference, use top of the self aftermarket parts or original equipment Ford parts. Do the job right and let us know when youíre near the 800k mark.
