I wonder if in the process of pounding that piece of valve around, the
#5 piston hurt itself. Cracked maybe? Or egged out the wrist-pin hole.
Bent the #5 connecting rod slightly?
When you back off the valve on #5, you're basically shutting down that
piston so its not getting combustion loading. See if the sound goes away
when you just pull the #5 spark plug wire. I'll bet it does....
