Is the Lexus 2jz engine a non interference engine?

Yes, the Lexus 2JZ engine is considered a non-interference engine. This means that in the event of a timing belt or chain failure, the engine's pistons and valves do not collide, preventing catastrophic damage. As a result, while such a failure can still lead to significant engine problems, it typically does not result in the same level of destruction seen in interference engines.
