To understand a ticking sound from the engine bay, compare it under normal, safe conditions: cold versus warm, idle versus steady speed, and light versus higher load. Record where the sound seems loudest and whether it changes with temperature or engine speed. Change one condition at a time so the result stays useful.
Do not create a risky test just to reproduce it. Check the specified oil level and service history; avoid guessing from sound alone.
Quick educational note
