* Valve-to-piston contact: The most common and devastating result. With the timing lost, the pistons can collide with the open valves, bending or breaking them. This requires extensive engine repair or a complete engine replacement.
* Bent connecting rods: While less frequent than valve damage, the sudden loss of synchronization can also lead to bent or broken connecting rods, again requiring major engine work.
* Damaged camshaft: The camshaft itself can be damaged due to the force of the impact or from the debris caused by the valve-to-piston collision.
Essentially, a broken timing belt in this engine is rarely a minor repair. It's a very expensive problem resulting in significant internal engine damage. The cost of repair is often more than the car is worth.
