A worn or cracked manifold can show up as a ticking noise on a cold start, an exhaust smell or soot around the flange. Before you replace this manifold, rule out a worn flange gasket or a loose downpipe joint, since either one can leak exhaust too, and leave any test that needs the engine running to a shop.
