ENGINE WAS REPLACED AT 87,000 MILES UNDER RECALL FOR HEAD GASKET FAILURE. 30,000 MILES LATER ENGINE HEAD BLEW UP AGAIN DUE TO THE PLACEMENT OF A HELICOIL IN THE RE-MANUFACTURED ENGINE. THIS HELICOIL WAS PRESENT IN THE RE-MANUFACTURED ENGINE FROM THE FACTORY. I CONSIDER THIS TO BE A DEFECT IN THE RE-MANUFACTURED ENGINE, AS THE HEAD SHOULD HAVE BEEN MACHINED BY THE FACTORY NOT JUST HAVE A HELICOIL STUFFED IN. THIS IIS THE CAUSE OF THE NEW FAILURE AND FOR REFUSES TO REPAIR. *NLM

WHEN THE CAR IS COLD, THE TRANSMISSION DOES NOT RESPOND TO MODERATE TO EXTREME ACCELERATOR PEDAL DEPRESSION. IT DOES NOT MATTER IF I AM IN FIRST OR 4TH GEAR OR THE SPEED. THE ENGINE IS SLOW TO RESPOND IN RPMS WHEN I ASK FOR IT, THEN GOES TO 2,000, THEN TO 3,000, BUT WITH NO CHANGE IN VEHICLE VELOCITY. THE CAR RESPONDS RELATIVELY WELL WITH LIGHT, INCREASING DEPRESSION TO THE PEDAL, BUT NOT TO ANYTHING THAT WOULD CAUSE A DOWN SHIFT. THE PROBLEM GOES AWAY AFTER 8 MILES OR SO OF CITY DRIVING. *JB
THE ENGINE LIGHT CAME ON AND THEN THE VEHICLE OVER HEATED. WHICH WAS CAUSED BY A BLOWN HEAD GASKET. *JB

I AM THE ORIGINAL OWNER OF THIS 1994 MERCURY COUGAR WITH 33,465 MILES AS OF MAR 4, 2002. AND THERE WAS A GENERAL RECALL ISSUED ON THE PROBLEM IN QUESTION WHICH INVOLVES THE POTENTIAL FOR A PREMATURE FAILURE OF THE ENGINE HEAD GASKET(S).AT THE TIME OF THE NOTICE THIS CONDITION WAS NOT EXPERIENCED AND NO ACTION WAS TAKEN. HOWEVER THIS CONDITION HAS NOW DEVELOPED AND IS CAUSING SEVERE ENGINE OVER HEATING. I HAVE BROUGHT THIS VEHICLE INTO THE LOCAL MERCURY DEALER AND THIS HEAD GASKET FAILURE DIAGNOSIS HAS BEEN CONFIRMED WITH THE REPAIR REQUIRING A COMPLETE HEAD GASKET REPLACEMENT AND ENGINE TAKE DOWN AND REBUILD COSTING 1400. AS OF THIS WRITING MY EFFORTS TO HAVE FORD MOTOR CO TO AGREE TO PICK-UP AND/OR AT LEAST ASSIST WITH THE PAYMENT OF THESE RELATED REPAIR FEES HAS BEEN DENIED. AND I WOULD VERY MUCH APPRECIATE YOUR REVIEW AND ASSISTANCE IN THIS MATTER.*JB
