problem details
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.
Buy replacement manifold. parts about 150; labor 180; 350-400 dollars worth repair.

Had the ticking noise for a couple of weeks before the pipe snapped. The exhaust sytem, as well as a majority of the undercarriage is pretty rusted. In the shop now for repair.
