There is not mush that you will be able to see once you remove the
plastic cover as you know from what you wrote as for removing the upper
half of the cylinder head unless you have access to all the tools
required to remove & reassemble leave it alone bring the car to either
your local Volvo specialist or to the dealer to find out what exactly is
going on

Exhaust leaks can sometimes make a metallic tapping sound. I agree
that a mechanic experienced with the car should take a look.
