you probably have bent valves in the head. If you were at the redline in 3rd and hit 2nd thats all it takes for the valves to float and the pistons to smash into them. Use an OBD2 scanner and it will tell you the code(s). You will probably at the very least need the head reworked. ooh and dont drive the car till its fixed. you will definatly need a new engine if you drop a valve.
