I over reved my the motor last week and my Vafc said it hit 9973RPMs. The car still seems to run great and idle is fine. I dynoed it last week and didnt see any kind of loss of power and the air/fuel is running perfect. The car doesnt smoke either but the only thing is that its making a soft tapping noise now. How much damage do u think im looking at?, Im going to take it to the shop monday but I was just curious to know if i was going to be looking a big problem. You think a vavle adjustment is in order?.
