1993 Land Rover Defender Problems

WHILE DRIVING MY 1993 LAND ROVER NAS DEFENDER 110 TO AN APPOINTMENT, I NOTICED SMOKE COMING FROM THE VEHICLE. THE PASSENGER COMPARTMENT COMPLETELY FILLED UP WITH SMOKE MAKING VISIBILITY POSSIBLE ONLY OUT THE OPEN DRIVER'S WINDOW. UPON OPENING THE HOOD, FLAMES POURED OUT. THE RIGHT SIDE OF THE ENGINE COMPARTMENT WAS ABLAZE. THE VEHICLE WOULD NOT SHUT OFF, DESPITE THE IGNITION HAVING BEEN SHUT OFF AND THE KEY HAVING BEEN REMOVED FROM THE VEHICLE. THE ONLY WAY TO SHUT THE ENGINE OFF WAS TO DISCONNECT THE BATTERY. THE FIRE WAS BURNING THE AC EQUIPMENT AND ENCLOSURE, VEHICLE WIRING AND HOOD, FENDERS, ETC. THE VEHICLE SUFFERED DESTROYED WIRING HARNESSES, THE ENGINE, THE ENTIRE AC UNIT, HOOD AND VARIOUS OTHER BODY PARTS, RESULTING IN A TOTAL LOSS. SOME PARTS ARE NO LONGER AVAILABLE. THE CAUSE OF THE FIRE WAS A PIN HOLE LEAK IN ONE OF THE OIL COOLER LINES. THE LEAK SPRAYS A FINE MIST OF HOT ENGINE OIL DIRECTLY ON THE HOT EXHAUST MANIFOLD. THE RESULT IS AN OIL-FUELED ENGINE FIRE. NOT BEING ABLE TO SHUT THE ENGINE OFF KEEPS OIL SPRAYING ON THE HOT EXHAUST MANIFOLD, CONTINUING THE FIRE. I HAVE COME TO FIND OUT A LARGE NUMBER OF DEFENDER 110'S HAVE HAD THIS PROBLEM. WHEN THE LINES RUPTURE, THE EFFECT IS SUDDEN AND CATASTROPHIC IS NO WARNING. LAND ROVER OFFERS NO RECOMMENDED SCHEDULE FOR CHECKING OR REPLACING THESE LINES. IN FACT, LAND ROVER WILL NOT DISCUSS THE ISSUE SAYING THE VEHICLE HAS BEEN DISCONTINUED. LAND ROVER'S ONLY ASSISTANCE WAS TO POINT ME TO A THIRD-PARTY THAT SELLS LAND ROVER PARTS. THE SAME CATASTROPHIC PROBLEM, ALTHOUGH IN LESSER NUMBERS, HAS OCCURRED ON DEFENDER 90'S AS WELL. LAND ROVER DISCOVERY'S, MANUFACTURED IN THE TENS OF THOUSANDS, ALSO UTILIZE THE SAME ENGINE. AS THE VEHICLES AGE, AND WITHOUT ANY MAINTENANCE SCHEDULE FOR CHECKING/REPLACING THESE LINES, COULD IT BE ONLY A MATTER OF TIME BEFORE THESE FIRES BECOME MUCH MORE COMMON? CONDITIONS: SUNNY, WARM SUMMER DAY; AC OFF; DRIVER'S WINDOW OPEN; RADIO ON; NORMAL DRIVING CONDITIONS. *NM

THIS IS MORE OF A GENERAL COMPLAINT REGARDING A MODEL TYPE, AS IT HAS COME TO MY ATTENTION THAT THERE HAVE BEEN A NUMBER OF INCIDENTS OVER THE PAST FEW YEARS THAT ARE NOT BEING ACKNOWLEDGED BY THE MANUFACTURER. THE INVOLVED VEHICLES ARE THE 1993 LAND ROVER DEFENDER-110, AND THE 1994-95 LAND ROVER DEFENDER-90. IT HAS BEEN FILTERING AROUND MOST ENTHUSIAST GROUPS THAT THESE TRUCKS ARE SUFFERING SOME TYPE OF EQUIPMENT FAILURE THAT IS CAUSING ENGINE BAY FIRES WHILE THE ENGINE IS RUNNING. THESE ALL SEEM TO OCCUR ON THE FRONT RIGHT SIDE OF THE ENGINE BAY, SPREAD RAPIDLY, AND ENTER THE PASSENGER COMPARTMENT WITHIN A SHORT TIME FRAME. NO COLLISIONS ARE INVOLVED IN THESE FIRES, THE GENERAL CONSENSUS IS THAT THE FIRES ARE MOST LIKELY CAUSED BY FAILING PRESSURIZED HOSES THAT ARE PART OF THE OIL COOLING SYSTEM. THE HOSES HAVE BEEN KNOWN TO SPLIT WITHOUT WARNING AND BECAUSE OF THEIR LOCATION WILL SPRAY FINELY MISTED ENGINE OIL ONTO THE RIGHT SIDE EXHAUST MANIFOLD. ANOTHER SUSPECTED CAUSE IS FROM THE POWER STEERING SYSTEM, WHICH IS ALSO LOCATED IN THE SAME AREA. THERE APPEARS TO BE ISSUES WITH THE MATERIALS USED IN THE OIL COOLER HOSES, AS A NUMBER OF LOW MILEAGE REPLACEMENTS HAVE ALSO FAILED WITH NO PRIOR SIGNS OF WEAKNESS OR DEGRADATION. I HAVE BEEN ABLE TO FIND NO RECORD OF ANY RECALL ON THESE PARTS, AND THE MANUFACTURER HAS APPARENTLY NOT ACKNOWLEDGED THIS ISSUE IN ANY WAY. *JB
