Why does my Ford Ranger's engine make a strange noise while idling?

I recently noticed that my Ford Ranger's engine is making a strange noise while idling. It sounds like a knocking or ticking sound. What could be the cause of this and should I be concerned?

It could be a sign of worn out engine components such as the rods or pistons. It's best to have it checked by a mechanic to avoid any major damage.

If your Ford Ranger is equipped with an automatic transmission, it could be an issue with the torque converter. Have it inspected to ensure there are no further problems.

You may also want to check the oil level and quality, as low or dirty oil can cause engine noises. Consider getting an oil change if needed.
