Do you know what RPMS they were holding the engine at? Some cars lasted longer than others because of RPMS. The "directions" state no higher than 2000 rpms, but some of those moron dealers doing this are redlining them or racing at very high speeds, blowing them up quickly....
Did you see the moron in that Mercedes W126 sedan racing the engine in that beautiful W126 sedan?
I know what you mean though... some of those Blazers and Cherokees blew up almost instantly.
I saw the Mercedes like mine meet the fate... now I want to see how a LS400 does it since I have one of those too.
