NHTSA Complaint #754450 — 1998 FORD ESCORT

DEALER WAS UNABLE TO DIAGNOSE VEHICLE PROBLEM OF HIGH PITCH WHINING SOUND THAT DEVELOPED AFTER THE ENGINE WARMED UP TO NORMAL OPERATING TEMPERATURE. IN MY OBSERVATIONS I NOTED THAT THE ENGINE WAS NOT CIRCULATING THE ENGINE OIL PROPERLY. WHEN PULLING OUT THE OIL DIPSTICK IT WAS APPARENT THAT A VACUUM PROBLEM EXISTED IN THE ENGINE. ALSO WHEN TAKING OFF THE OIL FILLER CAP A VACUUM SOUND WAS DETECTED. FINALLY I REMOVED THE PART AT THE TOP REAR OF THE ENGINE WHICH IS CONNECTED WITH HOSES TO THE AIR FILTER HOUSING. I IMMEDIATELY NOTED THAT THE ENGINE STARTED TO RUN SMOOTHER AND AFTER DRIVING THE VEHICLE FOR 2 HRS NO NOISE WAS DETECTED FROM THE ENGINE. IT IS OBVIOUS THAT THE VACUUM CAUSED BY THE DEFECTIVE FILTER DID NOT ALLOW THE ENGINE TO BE PROPERLY CIRCULATED IN THE ENGINE. THE VEHICLE RAN HOT AND THE COOLANT HAD TO BE TOPPED OFF. I FEEL THE DEFECTIVE FILTER HAS CAUSED ENGINE DAMAGE. I TOOK THE PART #F8CZ-6A768-AB TO THE LOCAL FORD DEALERSHIP PARTS DEPT AND HAVE ORDERED A REPLACEMENT. MY COMPLAINT IS THAT FORD AND THEIR DEALERSHIPS COULD NOT DIAGNOSE A PROBLEM THAT COULD LEAD TO COMPLETE ENGINE FAILURE DUE TO OVERHEATING.*AK
