The original engine was replaced at 90,000 under warranty, for what later were clearly timing chain noises. At the time, it seemed that the timing chain issues were not clearly understood.
The warranty replacement engine lasted 340,000 miles before I had it replaced with a rebuilt Powertrain engine, mostly because I could not resolve the balancer chain rattle. In hindsight, I should have just deleted the balanced chain and kept driving that motor. Did not want to cut the chain out and suffer severe engine balance and vibration issue.
I now have almost 70,000 miles on the current rebuilt motor.
Oil change interval is right at 3,000 miles. I try to keep everything in reasonable working condition. But lack the mechanical skills, tools, and confidence to remove the engine or the transmission.
Of course, many or most of the OEM parts have been repaired or replaced, I am currently on the third odometer, which has been replaced with entire clusters when the speedometer, odometer, and/or other significant gauge issues occurred. So the odometer will not show 500,000, although I track the total miles with adjustments as needed. At one point, I called several odometer shops to ask about resetting the mileage upwards. They more or less kindly told me I am crazy ( which is true).
I have not quite decided whether to keep the truck after 500,000 miles, or to change it up and get some sort of classic vehicle.
Thanks again for all of the help and insight from this Forum!
