Signs of Timing Chain Stretching:

Rattling noise from the engine.
Check engine light with timing-related codes (e.g., P0016 or P0017).
Poor engine performance or misfires.
Common Sprocket Wear Symptoms:
Worn sprocket teeth causing timing slippage.
Visible damage or uneven wear on sprocket surfaces.
Loose or misaligned timing chain due to sprocket degradation.
Diagram Display: Detailed visual of the timing chain setup, showing how sprockets, chain guides, and tensioners interact.
