"2003 DISCOVERY SERIES II OIL PUMP FAILURE" I HAVE A LOAD KNOCKING NOISE COMING FROM MY ENGINE, THE VEHICLE IS STILL RUNNING, AND OIL CHANGES, TREATMENTS ETC CANNOT STOP THE KNOCK.

THIS A $12,000 FIX FOR AN ISSUE THAT SHOULD HAVE BEEN A RECALL OR NOTICE TO THE PUBLIC. I HAVE OVER 300 POSTINGS ON LINE ABOUT THE SAME ISSUES BUT ALL IN 60 MINS OF LOOKING AND SURE THERE ARE THOUSANDS MORE. I'M NOT SURE HOW TO SEARCH FOR RECALLS OVER IN GREAT BRITAIN BEING THAT SOMEONE TOLD ME THAT?S WHERE MY VEHICLE WAS IMPORTED FROM WITH THE SALTY VIN NUMBER BUT ANY DIRECTION WOULD BE APPRECIATED. *TR
