You sure its a ticking sound or a bunch of marbles being thrown in an empty can.
If its a ticking noise might be a lifter problem needing shims, now if its spark knock/detonation can be a timing, fuel, and possibly a knock sensor going whack. To include an EGR problem.
Or a good engine flush-new oil/filter might work
