Why is my Ford Galaxy's engine making a ticking sound?

I've noticed that my Ford Galaxy's engine has been making a ticking sound lately. It seems to be more noticeable when the car is idling or at low speeds. Should I be concerned about this? How can I fix this issue?

The ticking sound could be due to a number of reasons such as low oil levels or an issue with the valves. It's best to have a mechanic take a look at it to determine the exact cause.

I had the same issue with my Ford Galaxy and it turned out to be a loose valve. The mechanic was able to tighten it and the ticking sound went away.
