Is a 1997 jaguar 4.0L XK8 an interference engine?

Yes, the 1997 Jaguar 4.0L XK8 is an interference engine. In an interference engine, the pistons and valves occupy the same space at different times, which means if the timing belt or chain fails, the pistons can collide with the open valves, potentially causing significant engine damage. Therefore, proper maintenance of the timing components is crucial to avoid catastrophic failures.
