Does the Toyota 1MZ-FE engine use a timing belt or a timing chain?

Question

Accepted Answer

The Toyota 1mz FE features a timing chain that works to synchronize the rotation of the crankshaft and camshaft(s), ensuring proper timing for the engine's valves to open and close during each cylinder's firing. This chain is positioned inside the engine and relies on oil lubrication for proper functioning, making oil maintenance essential. When a timing chain wears out and becomes loose, it can lead to a lack of synchronization between the valves and the engine, resulting in poor engine performance and a rough idle in the vehicle.
