Hi I just finished putting my new combo together and when I rev up the motor it makes a loud squeak or squeal. It only does it when it gets revved not at idle. When I rev it using the throttle body I hear the noise coming from the back of the motor, almost like it is in the bell housing or back of the block. I know it is not the throwout bearing cause I know exactly what that sounds like. Does anyone have any ideas what could cause it? Maybe a spun bearing or something? Any guesses or suggestions would be appreciated. Thanks in advance.
