Here's why:
* Valve Interference: The 3000GT engine has an interference design. This means that the valves and pistons share the same space in the cylinder head. When the timing belt breaks, the valves are no longer synchronized with the pistons. This can result in the valves colliding with the pistons, causing severe damage.
* Bent Valves: The most common damage caused by a broken timing belt is bent valves. The impact of the piston striking the valve can bend or break the valve.
* Damaged Piston: The piston itself may also sustain damage from the impact with the valve. This can include dents, cracks, or even holes.
* Damaged Cylinder Head: The impact of the piston hitting the valve can also damage the cylinder head, creating cracks or other damage.
Consequences of Engine Damage:
* Major Engine Repair: Repairing the damage caused by a broken timing belt can be very expensive. It may require replacing valves, pistons, cylinder head, and other components.
* Engine Failure: In severe cases, the damage may be so extensive that the engine is beyond repair.
Preventing Timing Belt Failure:
* Regular Maintenance: Follow the manufacturer's recommended timing belt replacement interval, which is typically around 60,000 to 100,000 miles.
* Inspection: Have your timing belt inspected by a qualified mechanic regularly.
* Listen for Warning Signs: Pay attention to any unusual noises coming from the engine, such as rattling or knocking sounds.
If you suspect your timing belt has broken, it's crucial to have the vehicle towed to a qualified mechanic immediately. Driving with a broken timing belt can lead to further damage and potentially catastrophic engine failure.
