A ticking type noise may be noted from the engine area due to an exhaust manifold that has cracked where the pipes are welded; cracked manifolds should be replaced.

ticking noise from cracked manifold that I was told was not uncommon for this year. No intention of replacing because of cost, but may try to patch cracks.
