Do you use 5w30 oil or 10w30 because i asked the question at the gm dealership once why my car was recomended for 5w30 rather than 10w30 and the response was that my lifters were machined so tightly that a 10w30 wont get into tighter areas to lubricate and mine were tapping so the guy at the dealership told me to run 0w30 until the tapping stopped then change back to 5w30 and it worked so that could be the case. finicky cars!
