Hey! I just bought a 97 sebring with a 2.5L v6 (82,000 miles) and I'm listening to the engine when it's in running and in park, and i hear a slight rapid ticking, which seems like it could be lifter tick. you cant really hear it with the hood down, but you can when you lift it. it's also not the loudest thing either. should I be worried?? first thing I thought was maybe it's time for a new timing belt but
