Your right on Peter, I'm thinking they forgot to put the screws back when they did the 30k service. Maybe they where hoping it would mess up the belts????? Hmmmm. |

I think I have an idea of what he's talking about. I've seen in only a few pictures of later 3_8 motors which had an additional thin tin plate behind the main timing belt cover, held on by some screws (right next to the valve cover). Seemed pretty flimsy to me and would still do a hell-of-a mess if it came off and into the belts....
Bo, I hope you used copious amounts of Loctite on those bolts now! |

Bo, Not to push a point but what backing plate in the timing belt area are you referring to? |

It was the back plate not the cover, but hey it was a good excuse to keep the car over 4000rpm at all time |

That'd make a hell of a rattle. |

Jesus Bo, The cover was just hanging there! You were lucky it didn't come off and end up in the belts. |

By the way --the rattle was a loose timing belt cover plate, it was missing all 6 screws....now on to the next odd noise! |

Bo
I used north coast exotics ( i think that is the name) in cleveland for a prepurchase inpsection. I did not by the car but was very happy with their through review of the car I was considering. Ask for Earl. |

Harmonic sounds, sounds produced by resonance, are usually the most difficult to identify. |

The noise was a metallic sounding rattle that was definitely a resonance. I never checked it from outside the car, I only heard it driving. It came and went as I went through the area of 3200 rpm. Unfortunately, in 5th, I had to choose my cruising speed to avoid the noise. As for diagnostics, we found that the the noise went away applying upward pressure the the headliner panel anywhere near (within 6 - 8") either side of the brake light. |

Craig, I would have never imagined that, was the noise metallic? could you hear it from the outside? |

I had a similar rattle that I originally thought was a heat shield. Tightening them did not cure it, then I found that gentle upward pressure against the headliner anywhere near the center brake light stopped the noise. Dropping the brake light assembly, and wrapping the wires in foam tape cured the problem. Apparently the wires resonated at about the same rpm, 3200. It made a big difference in my driving enjoyment. I credit Doug Pirrone at Berlinetta Motorcars with effecting the remedy. I hope the information helps other 328 owners. |

BO, Don't discount a loose baffle in the muffler. |

You may be heading toward shifter misalignment. I would check all of the linkage and make sure the linkage is secure and not working loose. It may be nothing but I would check it. |

I have an annoying rattle in my car under acceleration or steady rpms above 3500 or so. If I hold the the gear shift knob firm it stops. I am thinking loose linkage maybe? Suggestions? |

Daniel, The rattle can be heard free reving the engine or under exceleration. It may be something as simple as a loose timing belt cover. I will look into it this weekend. Now if I can just get my wife to hold the engine rpm at 4000 without freaking out(this may be harder to do than finding the rattle). |

The sound reminds me of a heat shield that has rusted on a old chevy's cat. converter. I will try to locate by using your method Magoo,I was just wondering if there is a certain part that is natorius with rattles in 328's, Thanks for the info |

As Magoo said, be more specific. Does it only rattle when you are off throttle and revs coming down in that range or will it occur on throttle too?
I had an annoying metallic rattle from 4500-4000 rpm off throttle which came from exhaust pipe which was fixed with padding at FOW, which they say is common. I have a smaller similar rattle now but it is weather dependent and doesnt bother me as now I know it is benign. |

If it occurs at certain RPMs as you said it sounds like a harmonic resonance. As Christian says it could be the timing belt covers, or some other metal object on the engine vibrating to the rpm reasonance. Can the noise be heard by reving the engine and listening in the engine compartment while laying your hand on various areas you may suspect of the noise? |

Probably one of the covers for the timing belts. |

Bo, What kind of a rattle? Be more specific. Is it a thumping noise, a metallic sound. That's a tough one without more info. Magoo |

I am reciving a rattle in the motor compartment between 3500 & 4000 RPM. Any guesses to what it may be? Also looking for a Ferrari mech. in the Cleveland Oh. area. |
