First you want to eliminate the simple easily overlooked causes. One would be that your oil level may be low so it wouldn't hurt to check. Another thing that may cause the tapping sound would be that your running too heavy of an oil weight, i believe for your vehicle the recommended is 5W-30, but generally if you were running say 10W-30 you would only get the tapping sound until the oil has circulated and warmed up. Let me know if this helps, if not we could look toward more mechanical type causes.
