Welcome to 2CarPros. That description sounds like internal part damage. The squeal would be something like a bearing or a lifter as the parts grind together. Either one can cause a rattle and wouldn't set a code unless it causes a problem in a monitored system. The easiest way to find the location would be to use a mechanics stethoscope and listen to the various locations to hear the sound. From there it would require taking the engine apart to determine exactly what parts are the issue
