Alternatively, you could loosen it up and see if it (the stud) is really loose. Also an oil analysis might help. Or, pulling #3 cylinder might allow you to eyeball the web. Elevated copper is a side effect of a cracked center main web. I know of one that flew at least 300 hours after a prop strike broke both of them loose. BTW, semantic error on my part. They are through studs. They are not through bolts, which is sorta what I was trying to say, so no need to loosen both cylinders.
