You have a 99 Contour that you purchased new and lately the valves are tapping more then before. They told you it is normal for some is there something that you can do to help that?

Slug build up from your motor oil would cause the valve's to "tap" more.
I would flush the engine using [http://www.auto-rx.com/index.html Auto_Rx Engine Cleaner].
Then use a Quality Synthetic. Good Luck and Remember.
Change Your Mind, Not Your Oil.
Use the First In Synthetic Motor Oil's.
