I have a couple questions. First, does everyone engine make a little noise, such as a lifter or mutter noise. Also, when you're not on the gas, does your rotor make noise, or like a slight "grinding" or "rubbing" noise??

 

Uh... lifter or mutter noise? you'll have to explain that one...

Rotor noise is pretty common.

 

WTF..."lifter or mutter noise..." In one word...no...

Rotors rub, but I never notice it with the engine running, it's still there, but my hearing must not be as good as yours... [&:]

 

What exactly does a mutter noise sound like anyway?

 

lol

 

Well, if you ever heard a car with a lifter noise, thats what it would sound like
