What amount of valve noise/clatter is considered normal? My M116 420 definitely has valve clatter, but to me it isn't bad. You can only really hear it when the hood is up and you kinda have to listen for it......it's not that loud to where you wanna say "Whoa, what is that!?!?" So should there be NO valve noise, or is a certain amount deemed normal?
