What all does it effect when the timing chain snaps in an 01 Toyota Echo?

When the timing chain snaps in a 2001 Toyota Echo, it can lead to severe engine damage, particularly if the engine is an interference type, which it is. This can result in bent valves, damaged pistons, and potentially a complete engine failure. Additionally, the loss of timing can cause the engine to stall, leading to issues with starting and overall vehicle performance. Immediate repair is necessary to avoid further damage and costly repairs.
