Check your LOWER chain. You will probably find a bit of slack in it.
Under deceleration it "flaps".
My 71 gtv did this and it went an additional 100,000 miles. I checked it
often but it never seemed to get any worse????

> I have an odd noise coming from the engine bay of my '89 Spider. It is a quick buzz or rapping sound and happens only at 17000 RPM. It is not always noticible when accelerating. It is a quick burst (about 1 second) when the RPMs drop quickly, or a constant sound if I keep the RPMs right at 17000. The noise does not happen haphazardly. It is there every time I pass 17000 RPM except when accelerating quickly May be there even then-just cannot hear it.
