Will a broken timing belt cause damage on ford 2.0 spi engine?

Yes, a broken timing belt on a Ford 2.0 SPI engine will almost certainly cause significant damage. The SPI (Sequential Port Injection) engine is an interference engine. This means that the pistons and valves share the same space in the cylinder head. If the timing belt breaks, the valves and pistons can collide, resulting in:

* Bent valves: This is the most common and likely damage. The valves will be bent or broken due to impact with the pistons.

* Damaged pistons: The pistons might be damaged by the impact with the valves. This can include dents, cracks, or even holes.

* Head gasket failure: The force of the collision can damage the head gasket, leading to leaks and engine failure.

* Damaged cylinder head: The cylinder head itself can be cracked or otherwise damaged.

* Broken connecting rods: In severe cases, the force can even break connecting rods.

Repairing this type of damage is usually very expensive, often exceeding the value of the vehicle. It's far cheaper to replace the timing belt at the recommended intervals than to deal with the consequences of a break.
