Do new timing chains make noise?

Excess slack in the timing chain can cause a rattling sound or even a clanking sound if the slack is severe enough to cause the chain to contact the timing chain cover. If the timing chain wear is great enough so the tensioner can no longer compensate for the slack, the noise may continue even after warming up.

What does a rattling timing chain sound like?
