So if the car drives fine why worry about a tick. I've had plenty of new cars that had "ticks" including my 1989 Sterling 827 SLi, which I bought in 90'. That is an Acura Legend motor which was pretty bullet proof and its still running strong almost 15 years tick and all. In fact, I've never put a penny into that car other than oil changes and gas and one timing belt change in 15 years. Maybe everyone is being overly critical. I don't know.
