Can the valves on a cavalier 2.2 liter engine bend if timing chain jumps?

Yes, the valves on a 2.2L Cavalier engine (specifically referring to the engines used in various years, typically those with a timing chain) can bend if the timing chain jumps or breaks. While not as common as interference engines with timing belts, it's still possible for the pistons to collide with the valves due to the misalignment caused by a timing chain issue. The degree of valve damage depends on how far the chain jumps.
