OIL PAN, LOWER BLOCK CASE OIL LEAKS THAT COST $2200.00 TO FIX.

OIL PAN, LOWER BLOCK CASE OIL LEAKS THAT COST $2200.00 TO FIX. A DEALERSHIP IN SAN ANTONIO TX SAID ALL 1995 THROUGH 1999 OLDS AURORA'S DID THIS AND THAT THE 4.0L V8 ENGINE HAD TO BE REMOVED IN ORDER TO REPAIR THE PROBLEM. THE GASKETS COST AROUND $35.00 DOLLORS BUT THE LABOR COST $2200. GM TOLD ME IT WAS NOT TRUE THAT ALL THE OLDS AURORA'S FROM 95 THRU 99 HAD SUCH A PROBLEM. THIS CAR WAS DESIGNED SO THAT AN OWNER THAT HAS MECHANICAL SKILLS WOULD NOT BE ABLE TO REPAIR THIS PROBLEM AT THEIR HOME WITH OUT REMOVING THE ENGINE. I FEEL THIS IS A BAD DESIGN OF THE ENGINE AND CAR. I FEEL THAT THE GASKETS ARE NOT HOLDING UP DUE TO THE FACT THAT THESE CARS RUN AT A VERY HIGH TEMPERATURE BETWEEN 225 DEGREES F. TO 250 DEGREES F AT ALL TIMES. I WOULD VENTURE TO SAY THAT THE GASKET MANUFACTURES DID NOT INTEND ON THE GASKETS INSTALLED IN THESE CARS TO BE UNDER A CONSTANT HEAT LOAD OF 225 DEGREES TO 250 DEGREES F. THE HIGH HEAT RANGE CAUSES OTHER PROBLEMS AS WELL. GM SAID TO PAY THE PRICE OR NOT BECAUSE THEY HAD NO OBLIGATION TO REPAIR THIS PROBLEM.

SOME PASSENGER VEHICLES EQUIPPED WITH 4.0L V8 ENGINES HAVE A CONDITION IN WHICH THE NYLON TUBING USED IN THE FUEL RAIL CONSTRUCTION MAY DEGRADE AND CRACK. ADDITIONALLY, THE 1995 MODEL YEAR USES A UNIQUE UNDERHOOD FUEL RETURN LINE THAT MAY CRACK. CRACKING OF THE FUEL RAIL OR RETURN LINE TUBING CAN RESULT IN A FUEL LEAK INTO THE ENGINE COMPARTMENT.
Consequence & remedy
Consequence: FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL INSPECT AND, IF NECESSARY, REPLACE THE ENGINE FUEL RAIL WITH A NEW STAINLESS STEEL FUEL RAIL. DEALERS WILL ALSO INSTALL A REVISED CHASSIS FUEL RETURN LINE. THE RECALL BEGAN ON JUNE 2, 2004, FOR 1996-1997 OLDSMOBILE AURORA VEHICLES. OWNERS OF 1995 CADILLACS AND 1996-1997 OLDSMOBILE AURORA WERE SENT LETTERS ON AUGUST 6, 2004.

THE FUEL RAIL ASSEMBLIES USED IN THE SUBJECT VEHICLES WERE MANUFACTURED BY DANA.THE FUEL RAIL JUMPER TUBES WERE MADE OF MONOLAYER NYLON 12 (PA12).IN MODEL YEAR (MY) 1998, THE JUMPER TUBE MATERIAL WAS CHANGED FROM PA12 TO M-BOND (A MULTI-LAYER PTFE/PA12).IN ADDITION, ALL SERVICE PARTS PRODUCED SINCE THE END OF PRODUCTION 1997 USE THE M-BOND JUMPER TUBES. MATERIAL ANALYSIS PERFORMED BY DANA ON FAILED FUEL RAILS SHOWED THAT THE MONO-LAYER NYLON 12 JUMPER TUBES ARE SUSCEPTIBLE TO ENVIRONMENTAL STRESS CRACKING (ESC).GM BELIEVES THE ESC IS A RESULT OF HEAT, TIME, ALCOHOL BLENDED FUEL, FUEL PRESSURE CYCLING, AND DESIGNED IN STRESS. EIGHT OF THE GM COMPLAINTS ARE DUPLICATIVE OF ODI COMPLAINTS.ODI HAS RECEIVED 77 OF IT'S 123 COMPLAINTS IN THE PAST 12 MONTHS.FUEL RAIL PART SALES OVER THE LAST THREE YEARS RANGE FROM 3.0 PERCENT OF PRODUCTION FOR THE MY 1997 CADILLAC VEHICLES TO 13.1 PERCENT FOR THE MY 1995 AURORAS.AT LEAST ONE OF THE FIRE INCIDENTS OCCURED WHILE THE VEHICLE WAS PARKED WITHIN A GARAGE ATTACHED TO THE CONSUMERS HOME.THE FIRE RESULTED IN DAMAGE TO THE DWELLING AS WELL AS THE TOTAL LOSS OF THE VEHICLE.THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS.
