Why does my Nissan Juke's engine have a ticking noise?

I recently noticed that my Nissan Juke's engine has a strange ticking noise. It seems to be coming from the top of the engine, near the valve cover. Is this something I should be worried about?

The ticking noise could be caused by a variety of issues, such as low oil pressure or a faulty valve. It's always best to get it checked out by a mechanic, just to be on the safe side.
