Hello thanks in advance for any helpful answers. My wife and I were stopped at a traffic light in our 05 Cobalt 2.2l, we started to go but lost power instantly. Turned the motor lover a few times and noticed the was no resistance (compression). Pulled the valve cover and saw the valve rockers weren't touching the cam shaft. So I'm assuming the valves are bent..!? Right. The main or question do you think the pistons are bad too?
