    With 84,000 miles there suddenly appeared a loud tapping/knocking
    sound from the #5 cylinder upper engine area. No smoking, reduced
    power, tapping is reduced slightly under load. Engine has only been
    idled since noise began. There was no warning , the noise appeared
    suddenly. I have checked the plug and coil and am about to remove
    valve cover to inspect. It would seem to be coming from the Valve area
    of the head but my experience shows very little in this area would
    cause the loud knock. Has anyone experienced such symptoms before with
    a Volvo 5 cylinder turbo?

    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.
