A cracked or leaking manifold can show up as a ticking noise at a cold start, an exhaust smell, or cracks you can see with the engine off and cool. Before you replace the manifold, rule out a leak at the downpipe joint or elsewhere in the exhaust, since a leak in another spot can sound much the same.
