The tick noise that everybody talks about, is that when the car is at idle and you lift the hood and the engine is going tick tick tick tick tick when idling? If so, i think that's normal for these modern engines. When I was shopping for my Stang, the few that I checked out all did this. They were all low mileage preowned cars.
