Everything MGK says is true. I'd add that the con rods and their bearings are under tremendous loads at such a high overrev (if it really happened - other people have noted bogus numbers in the ECU log--definitely take it with a grain of salt), so I'd look carefully at hot idle oil pressure as well. 'Hot' here is defined as 'oil above 180 deg F,' which might be a challenge in winter. That said, if it doesn't have hot idle rod knock, the bottom end is probably fine, so your primary concern is a close encounter between valves and pistons, as MGK says. Does anybody have any idea where valve float RPM is on a 2ZZ-GE anyway?
