Will the valves bend when the chain breaks on 2004 320i 2..2L BMW engine?

Yes, in the 2004 BMW 320i with the 2.2L engine, if the timing chain breaks, it can cause the valves to bend. This is because the engine is designed with a non-interference fit, meaning that the pistons and valves occupy the same space at different times, and when the timing chain fails, they can collide. This can lead to significant engine damage, requiring costly repairs. Regular maintenance of the timing chain is crucial to prevent such failures.
