ive been noticing this taping noise wich sounds like a valve that needs adjusting. i used an automotive scope to listen to it and its on the front bank. intake side. first valve away from the water pump pully. what could make this happen? dont n*s have self adjusting lifters? will it hurt anything?

The lifters on a N* have no adjustment. Does it tap all the time or just when it's cold? My car sounds like a cement mixer when you start it, but once it's warm, it purrs like a kitten.
