When the timing chain breaks on a 1995 2.3 liter dohc Chevy cavalier does it bend valves?

Yes, a broken timing chain on a 1995 2.3L DOHC Chevy Cavalier will almost certainly bend valves. These engines are interference engines, meaning the pistons and valves share the same space in the cylinder. When the timing chain breaks, the valves are no longer synchronized with the piston's movement, leading to a collision and bent valves (and likely other damage).
