Good stuff to consider. Makes me think getting a warranty might not be such a bad idea!
I'm used to oil consumption, but the engine failure issue sure is scary. I don't know if a leak down test would show signs of eminent failure but i'd get one any way as part of the pre purchase inspection.
Anyway thanks for the detail.

a warranty may not be too bad but finding one that is not a total rip off is not easy. Check requirements you may pay for one and then find out your vehicle was not qualified in the 1st place
