The dephaser is a oil driven cam pulley as such, it advances and retards the timing (But not for performance like Vtec)

They normally rattle/sound like a diesel when ilding when warm, but the noise should go away once you rev it over 1500 rpm as that is when it should do it's thing as it where.

Bear in mind they can also make noise from cold, but more likely when warm
