Metallic Rattling My 03 LX Sedan has 230,000 miles on it. Runs pretty well TBH but the rattling is driving me insane. One persistent source of rattling sounds like bits or metal being rattled in a tin can. If the car is in park and I rev the engine the normal revving sound is followed by the rattling. When driving, acceleration in general results in this sound. Best case scenario heat shield? Could be catalytic converter or transmission? I checked under the hood and looked at the heat shield on my cat and it's not pretty but it's on there pretty firmly. Sounds like it's coming from the front part of my car. Deep in engine or front undercarriage. Helpers? Thanks |
Re: Metallic Rattling Common for heat shields on and around the exhaust system to rust out and cause noise like you describe. Also check the front brake rotor dust shields for rusting off. |

Re: Metallic Rattling Use a board or similar to whack the muffler and resonator slightly. Blown catalytic can end up in there and it’s hard as glass and will rattle. |
