And try the headlight too...that thing can rattle and sound like it is coming from the engine as well. I thought my top end was coming apart....until I placed my hand on the headlight bucket and squeezed the outer ring against the bucket. The cure for me was to place a thick piece of tape on each of the tabs that holds the ring on.
