2002 PONTIAC TRANS AM Engine And Engine Coolingengine Problems

DT: THE VEHICLE WAS PARKED WHEN THE CONSUMER STARTED IT AND COULD HEAR AN EXPLOSION SOUND COMING FROM UNDER THE HOOD. WHEN LIFTING THE HOOD COULD SEE OIL COMING FROM ALL OVER. WHEN SHE TOOK IT TO THE DEALERSHIP, THEY VERIFIED THAT THE MAINTENANCE HAD BEEN KEPT UP. THEY TOLD HER THAT THEY WOULD REPLACE THE MOTOR WITH A USED MOTOR. THE CONSUMER WAS CONCERNED THAT THE SAME PROBLEM WILL HAPPEN AGAIN. THE CONSUMER CONTACTED THE MANUFACTURER, THEY UNDERSTOOD HER CONCERN AND STATED THAT THEY COULD NOT HELP HER BECAUSE HER WARRANTY WAS WITH SOMEONE ELSE. THERE HAVE BEEN NO PREVIOUS PROBLEMS WITH THE ENGINE. *AK

ENGINE KNOCK; PISTON SLAP. CONTINUOUS TAPPING SOUND FROM THE ENGINE THROUGHOUT THE TEMP RANGE. *NLM

CONSUMER STATES WHEN ACCELERATING ENGINE LOOSES POWER. CAUSE UNKNOWN. *AK WHEN CONSUMER ATTEMPTS TO PASS A VEHICLE, THE RPM GOES DOWN. THE ENGINE WOULD DIE DOWN TO 50 MPH FORCING THE CONSUMER TO PULL BEHIND THE VEHICLE HE TRIED TO PASS. SINCE DEALER COULDN'T DUPLICATE THE PROBLEM, VEHICLE WAS UNABLE TO BE REPAIRED. *PH

I HAVE A KNOCK IN MY ENGINE APPEARING TO BE COMING FROM THE NUMBER 1 PISTON AND CYLINDER AREA. ONE DEALER CALLS IT PISTON SLAP, WHICH I HAVE READ UP ON AND IT SAYS THAT IT GOES AWAY AFTER IT WARMS UP, MY KNOCK CAN BE HEARD AT ALL TIMES OF ENGINE OPERATION. GM SAYS THERE ARE TEFLON COATED PISTONS AVAILABLE ONLY FOR THE CORVETTE LS1 ENGINE AND NOT MY TRANS AM LS1 ENGINE. I HAVE DEALT WITH ONE DEALER IN OAK HARBOR WA THAT IS BOTH A CHEVY AND PONTIAC SERVICE CENTER. I REFUSE TO USE THIS DEALER EVER AGAIN BECAUSE THEY TRY TO PAWN IT OFF AS PISTON SLAP AND THAT IT IS NORMAL TO HAVE. I HAVE A HIGH PERFORMANCE ENGINE I SHOULD NOT HAVE ANY KNOCKS IN IT, ESPECIALLY SINCE IT IS WORSENING AND I AM ABLE TO FEEL THE KNOCK THROUGH THE GEAR SHIFT HANDLE....
