What happens if you over rev your engine?
If an engine goes overspeed, commonly called “over-revving”, damage to the piston and valvetrain may occur when a valve stays open longer than usual. Valve float can possibly result in loss of compression, misfire, or a valve and piston colliding with each other.

It will wear the engine, specially if it’s not yet on temperature, it will wear oil, if the car is automatic it will stress the torque converter and the brakes (if you’re revving with gear engaged) or just the torque converter, it will stress all the friction bearing because sudden acceleration (and negative …
Does high rpm clean engine?
