Where is the noise coming from?
Does it changes with engine speed?

The engine area, and it seems to be just during idlning

Ticking noise during idling are usually due to valve clearances. Have the valve clearances checked and shims replaced if there are signs of abnormal wear.

Ok thank you very much. Does this mean change valve cover gaskets as well?

You're welcome.
When valve cover is removed, the gaskets is recommended to be replaced, unless it has only been installed recently.
