1993 CADILLAC SEVILLE Engine And Engine Cooling Problems

THE CAR STALLED AND WAS TOWED TO A REPAIR SHOP. THE NEXT DAY IT WAS BROUGHT INTO THE SHOP. THE MECHANIC TURNED THE IGNITION SWITCH TO START, AND THE INTAKE MANIFOLD EXPLODED, SENDING PIECES OF THE MANIFOLD THROUGHOUT THE SHOP. THE EXPLOSION ALSO DAMAGED THE POWER STEERING PUMP. IT WAS LATER DISCOVERED THAT THE CAUSE OF THE EXPLOSION WAS FUEL THAT HAD COLLECTED IN THE MANIFOLD DUE TO A CRACK IN THE PLASTIC FUEL RAIL. SOMETIME DURING 1993 THE MANIFOLD WAS RE-DESIGNED TO ALLEVIATE THIS PROBLEM, HOWEVER, THERE WERE NO RECALLS, LEAVING THOUSANDS(?) OF CARS WITH THIS POTENTIAL PROBLEM. I DID FIND A DEALER SERVICE BULLETIN CANCELING AN EXCHANGE PROGRAM FOR THE INTAKE MANIFOLDS FOR THIS MODEL AND YEAR. (NO: 93-I-58). *LA

THE INTAKE MANIFOLD BLEW UP IN A PUFF OF SMOKE WHEN I TURNED THE KEY, BLEW A HOLE RIGHT THREW THE END OF THE MANIFOLD! *NLM

THE ENGINE DEVELOPED A NOISE DUE TO A DAMAGED PISTON WRIST PIN ON A CYLINDER AS THE RESULT OF A DESIGN FLAW, AS STATED IN SERVICE BULLETIN 47-61-42 ISSUED 01-FEB-95. YH
