It is difficult to address your question without more information.
What engine do you have?
What kind of noise are you hearing and when does it go away? (eg. Loud ticking, dull knocking, high rpm, etc.)
And, why does your husband say that the noise is normal? He may know what the source of the noise is.
Did you check for any engine codes?
All of this information will help all of us to better evaluate your issue.
Thanks.
PS. Fill in your information so we can better assist you.
