| Description of the problem | The exhaust manifold bolts that thread into the cylinder heads holding the cast iron exhaust manifolds in place onto the heads break off under normal road conditions. The bolts break off and were causing an exhaust leak. My vehicle's exhaust was coming inside the vehicle making occupants ill. The steel manifold bolts are undersized for the application, and being used on iron manifolds mating to aluminum cylinder heads. I have to pay the $1000+ repair cost to fix an apparent manufacturing failure that should be recalled. No only do the broken bolts cause exhaust leaks and noise, but puts the vehicle in this condition as a possible fire risk. |
