HELP! accidental overev!

[pushrod]

It's possible that the valves did touch the pistons ever so slightly, in which case the pistons would be slightly work hardened and if stressed in the future, may shatter.

Also, the highest RPM ever reached is logged by the ECU, apparently. In this case, good luck with any future engine warranty claims.

My sympathy-o-meter didn't hit the redline reading the original post. In fact, it stalled. Real men screw up their 110mph upshifts on the track, not on public roads.

1 - Dont believe anything someone tells you on the internet (That includes me).

2 - An overrev condition will usually over stress components such as rod ends, pistons, or rocker arms.
just because nothing broke it doesnt mean that components werent overstressed.
You dont know until something breaks.

3 - change the oil, cut open the filter, look for debris. If no extra debris, just drive it more carefully and enjoy.

Once you realize that your car really is just a tool (like a hammer) you'll quit worrying and swing the damn thing.
If you break it, youll buy new handle or youll pitch it and buy a whole new one.

I read the first post and then looked for this comment.

maybe rpm data is logged somwhere but using techstream that dealer have it does not appear to be able to access that data. All log data in ecu that is accessable via techstream is erased on ecu reset ie poer removal, even before a reset no max rpm data is accessable. other stuff like dtc codes time since reset time since tdc actice is accessable but is also erased on reset.

dealers have tried to bluff guys, but they were unable to produce log evidence.
they may still win as their techs\engineers will analyse the failed components and they may gain enough from that to determine it was an overrev, like dents in piston crowns. or bent valves ect

Drove the car like I stole it, two days after I got it! No issues whatsoever!
