Answers :

Try a higher grade octane fuel and see if that eliminates the noise some. Wait til it's almost empty and put the highest grade fuel and drive for a bit and see if you notice a any change. Sometimes the valves get dirty and you start getting a bit of a tap. Also try an additive that removes carbon deposits. Sometimes it's normal when you cold start the vehicle to hear some tapping, but after warm up it should go away.
