Well I did a follow up on the replacement motor I ordered and was able to cancel it after running a carfax and finding the motor had 97000 on it in 2008. It had a salvage/recontructed title at that time. It was then sold and driven again with no increase in mileage at all through 2017 when the salvage yard took it after being totaled out again this year.
I am in this for the long haul and want a motor I can trust. I can't find anything used worth going after. So now I am looking for a remanufactured engine.
