A ticking noise indicates excessive clearance in something, and in 37 years of being a tech, I have yet to encounter a clearance issue that healed itself. Excessive clearance causes premature wear, which causes more clearance. You get the idea. I would be wary of any ticking after engine work, let alone if it were to be still present after 4000 miles.
Caveat emptor, my friend. Doc
