Actually sometimes I do and I know it's normal. Like my neck cracking or my ears popping in an airplane

Cars are mechanical, so sometimes popping sounds are normal. Maybe that nice wonderful 4-5krpm intake sound the macht schnell filter gives isn't normal! Or the mechanical whirring sound when slowly turning at full lock isn't! OH NOES!

You can't be too detailed to the sounds of the car and since its so rare, and the car does have its own unusual characteristics I wanted to check.

Do you have any information on why this sound is not normal?
