just noticed a tapping noise in my 98 cobra. it does not seem to be coming from under the hood and it does not get faster or louder with rpm's. i just can't seem to locate the source. it is driving me nuts. anybody got any ideas?
If it's not originating from the engine, then is the vehicle in motion during this tapping sound? Or does it happen at idle with the car stopped? It could be an exhaust pipe or flange tapping the underneath of the body/frame. It could also be an exhaust leak, although a tapping sound from an exhaust leak would usually be where the headers mate with the heads and not necessarily further down the pipe.
