Back then the ST would have been made by Champ, and depending on application could likely have been an ecore using a nitrile combo valve. In that case, some start up rattle wouldn't be surprising. Not saying that's acceptable, just not surprising imo.
I understand. The good part of that whole deal was, I changed the filter only to a MC FL 400 and the start up clatter was gone. At that point I have only used MC filters in my Fords with success. That was 12 or so years ago.
