Notorious for cracked exhaust manifolds. I've replaced both of mine so far. Typically the passenger side goes first. Mine happened about a year apart. If it's ticking AFTER it's warmed up, though, it might not be the manifold. They normally tick until warmed up, then quit. If it is a manifold, and it's left go, it can erode the bolt flange/port on the head. Then you'll never seal it. They can be spendy to change, at about $900 per (dealer).
