I HAVE A 2002 CHEVROLET SILVERADO 2500HD LT EXT. CAB LB7 DURAMAX 5 SPEED ALLISON TRANSMISSION, IT HAS 114000 MILES ON IT. THIS TRUCK HAS BEEN SERVICED AS DIRECTED SINCE NEW. THE TRUCK STARTED USING LOTS OF FUEL, AT AN IDLE IT SERGED BETWEEN 700 & 900 RPM'S, AND OIL STARTED BLOWING OUT THE BLOWBY TUBE. I HAVE JUST FOUND OUT THAT 3 FUEL INJECTORS ARE LEAKING FUEL, WITH A POSSIBLE HEAD GASKET LEAK,FILLING MY CRANKCASE WITH DIESEL, CAUSING OIL TO BLOW OUT ALL OVER THE TRUCK, ROAD AND WHATEVER ELSE IT CAN LAND ON. WHILE INVESTIGATING WHAT TO DO, TO FIX THE TRUCK I'VE FOUND 3 OTHER PEOPLE I KNOW THAT HAVE DURAMAX'S, AND THEY ARE GOING THROUGH THE SAME PROBLEMS. IT'S GOING TO TAKE ME A YEAR TO SAVE THE MONEY I NEED TO FIX THIS TRUCK. I'M EVEN GOING TO DO THE WORK MYSELF. IN MY OPINION GM SHOULD BE ASHAMED. THEY SHOULD AT LEASED PAY FOR THE PARTS. THE CHEAPEST INJECTORS I'VE FOUND ARE $225.00 APIECE WITH A $125.00 CORE CHARGE. IT'S RECOMENDED THAT ALL 8 INJECTORS BE REPLACED AT ONCE. I'VE ALSO BEEN TOLD THESE ENGINES HAVE DEFECTIVE HEAD GASKETS. THAT WILL COST ANOTHER $600.00 FOR PARTS, AND $110.00 FOR SPECIAL TOOLS I NEED TO DO THE JOB. WHEN I FORKED OVER THE $40,000 CASH INHERITINCE MONEY TO BUY THIS TRUCK, I DIDN'T SIGNUP FOR THIS. *TR

I OWN A 2002 CHEVROLET 2500 HD WITH THE 8.1 (8100 VORTEC) ENGINE. I HAD BEGAN HAVING PROBLEMS WITH THE ENGINE STALLING WHILE DRIVING PERIODICALLY. IT BECAME A FREQUENT PROBLEM. I HAD THE VEHICLE SCANNED AT A LOCAL AUTO PARTS STORE WITH NO FAULT CODES SHOWING. I LEARNED THE CRANKSHAFT POSITION SENSOR WAS AT FAULT BY DOING SOME ONLINE RESEARCH. I ALSO LEARNED THE SAME ENGINE HAD A RECALL IN 2001 AND NOT 2002 THE FACT THE VEHICLE STALLS DURING OPERATION IS A SERIOUS HAZARD . CHEVROLET NEEDS TO TAKE RESPONSIBILITY FOR THIS AND RECALL THESE VEHICLES . I CHANGED MY OWN , BUT CHEVROLET NEEDS TO FIX THIS FAST BEFORE SOMEONE DIES IF THEY HAVEN'T ALREADY ! *TR

I HAVE A 2002 CHEVY SILVERADO 2500HD NEARLY CAUGHT FIRE YESTERDAY. A LEAK DEVELOPED IN THE POWER BRAKE BOOSTER/HYDRO-BOOST SYSTEM AND POWER STEERING FLUID WAS LEAKING ONTO MY HOT EXHAUST MANIFOLD. SMOKE WAS POURING FROM UNDER MY HOOD. I SUSPECT A SMALL FIRE BECAUSE OF THE AMOUNT OF SMOKE. BY THE TIME I PULLED OFF THE ROAD AND OPENED THE HOOD ALL I SAW WAS SMOKE FROM SOMETHING LEAKING ON THE MANIFOLD. I GOT ONLINE AND FOUND THIS RECALL INFORMATION FOR 2004-2005 CHEVY TRUCKS BUT NOT 2002. I WANTED TO INFORM YOU THAT THERE MAY BE A NEED TO RECALL 2002 SILVERADO TRUCKS AS WELL. RESEARCHING DIESELPLACE.COM AND DIESELPAGE.COM THIS PROBLEM IS COMMON AND WIDESPREAD. ---------------------------------------------------------------------------------- MARCH 2005 DEAR CHEVROLET CUSTOMER: THIS NOTICE IS SENT TO YOU IN ACCORDANCE WITH THE REQUIREMENTS OF THE NATIONAL TRAFFIC AND MOTOR VEHICLE SAFETY ACT. REASON FOR THIS RECALL: GENERAL MOTORS HAS DECIDED THAT A DEFECT, WHICH RELATES TO MOTOR VEHICLE SAFETY, EXISTS IN CERTAIN 2004 MODEL YEAR CHEVROLET KODIAK AND CERTAIN 2004 AND 2005 MODEL YEAR CHEVROLET AVALANCHE, EXPRESS, SILVERADO, AND SUBURBAN VEHICLES. ON SOME OF THESE VEHICLES, THE HYDRAULIC BRAKE BOOSTER'S PRESSURE ACCUMULATOR MAY CRACK AND/OR SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL VEHICLE OPERATING CONDITIONS. IF A SEPARATION WERE TO OCCUR AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. IN ADDITION, THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT. WHAT WILL BE DONE: YOUR CHEVROLET DEALER WILL INSPECT THE HYDRAULIC BRAKE BOOSTER, AND REPLACE IT IF NECESSARY. THIS SERVICE WILL BE PERFORMED FOR YOU AT NO CHARGE. *TR

I DO NOT KNOW IF THIS CAUSED AN ACCIDENT WITH THE VEHICLE BEHIND ME OR NOT. HOW MANY ACCIDENTS COULD HAVE HAPPENED AND NO ONE REALIZED IT WAS FROM THE OIL OF OUR TRUCK. FURTHER MORE CHEVY KNOWS THIS IS A PROBLEM. SO HOW MANY PEOPLE HAVE TO GET HURT OR DIE BEFORE THEY TAKE CARE OF THE PROBLEM. OF EVERYONE I HAVE TALKED TO ONLY ONE PERSON WAS UNDER WARRANTY AND THEY MADE IT BY 14 DAYS. CHEVY HAS A PROBLEM AND NEEDS TO FIX IT, AND NOT WITH AN EXTENDED WARRANTY. THIS IS MY FIRST CHEVY AND WILL BE MY LAST. MAYBE THAT IS WHY CHEVY NEEDED BAIL OUT MONEY

EXHAUST MANIFOLD BOLTS ON 2002 CHEVROLET 2500 HD 6.0 L V8 ARE BROKEN AT THE BACK BOLT ON THE DRIVERS SIDE. THE PASSANGER SIDE EXHAUST MANIFOLD IS CRACKED BETWEEN THE 3RD AND 4TH BOLT FROM THE FRONT. I REPLACED THE BOLTS ON THE DRIVER SIDE, EXCEPT FOR THE BACK ONE THAT IS SHEARED OFF FLUSH WITH THE CYLINDER HEAD. THE ONLY WAY TO GET THIS PARTICULAR BOLT OUT IS TO REMOVE THE CYLINDER HEAD FROM THE ENGINE SO THAT A MACHINE SHOP CAN DRILL OUT THE OFFENDING BOLT. THE REPLACEMENT BOLTS THAT I PURCHASED FROM THE GM DEALER WERE A MUCH STURDIER BOLT THAT HAD A MUCH LARGER HEAD ON THE BOLT. TO ME THIS INDICATES KNOWLEDGE THAT THERE IS A PROBLEM AND THAT GM IS AWARE OF IT. THIS WILL MOST CERTAINLY LEAD TO AN EXHAUST LEAK THAT WILL CAUSE THE CHECK ENGINE LIGHT TO COME ON. A VEHICLE WITH THE CHECK ENGINE LIGHT ON CANNOT PASS A FIELD EMISSIONS TEST AND WILL RESULT IN A REVOCATION OF THE VEHICLES REGISTRATION UNTIL THE PROBLEM IS CORRECTED. THIS IS NOW A SERIOUS PROBLEM THAT IS VERY EXPENSIVE TO REPAIR. GM SHOULD BE HELD ACCOUNTABLE FOR THE POSSIBLE EPA VIOLATIONS THAT THIS WELL DOCUMENTED ISSUE IS NOW CAUSING. THIS VEHICLE ONLY HAS 70,000 MILES ON IT, VERY LOW FOR A 2002.
