If the timing belt broke on a 2001 Ford ZX2 2.0 dohc is motor junk or are they non interference motors?

The 2001 Ford ZX2 with the 2.0L DOHC engine is an interference engine. This means that if the timing belt breaks, the pistons can collide with the valves, causing significant damage to the engine. It's highly likely that a broken timing belt will result in bent valves and other internal damage, requiring a costly repair or engine replacement. It's not considered a "non-interference" engine in this context.
