There is no need to worry unless you start to hear some type of sound. If you have leaks on the engine at the timing cover then this is a gold time to have the work done or at least inspect the guides. Even if they are in tact they do get brittle and then tend to break. Again if your vehicle is absolutely quiet then don't worry about it at this time.
