My point is, if i buy a car and pay a pretty decent amount of money down on it, why is it i have to be "surprised" by a noise that was not there when i test drove the car? It may not bother you, but it does me. The crickets are a pain in the butt, especially when im next to something. You may not have had anyone bring it up, but I have, and having to explain it as a "normal noise" has gotten me confused stares....
Everyone has their own views, but to me, chirps and squeals are not something I would classify as a normal noise from a motor. Especially a brand new motor.
