2002 CHEVROLET SILVERADO 1500 HD Engine Problems

3 EXHAUST MANIFOLD BOLTS BROKE OFF MANIFOLD. *TR

STARTED TO HEAR ENGINE EXHAUST GETTING LOUD, STARTED TO LOOK FOR EXHAUST LEAK AND FOUND THAT # 8 AND #7 PISTON LEAKING AT EXHAUST MANIFOLD DUE TO BROKEN BOLTS AND THEN ENGINE ERROR CODE O2 SENSOR BANK 1 WILL NOT TURN OFF, CAN NOT GET TRUCK TO PASS INSPECTION HAVE FOUND OUT OTHERS TRUCK OWNERS HAVE SAME PROBLEM. *TR

AT APPROXIMATELY 50 MPH COOLANT LOSS FROM A CRACKED CYLINDER HEAD SENT A SIGNAL TO THE ECM TO SHUT DOWN THE ENGINE WHICH CAUSED THE LOSS OF POWER STEERING AND CONTROL. WEATHER CONDITIONS WERE SNOW AND WIND AND I WAS FOLLOWING TWO DRY TRACKS IN THE ROAD, UPON LOSS OF POWER THE TRUCK DRIFTED ONTO AN AREA OF ROAD COVERED IN SNOW WHICH NEARLY CARRIED ME OFF INTO A DITCH. ON A DRY DAY IF THIS HAD OCCURRED INERTIA WOULD HAVE TAKEN ME ON TO A SOFT SHOULDER SO IN THIS INSTANCE THE COLD WEATHER AND SNOW ACTUALLY HELPED THE TRUCK FROM DRIFTING TOO FAR OFF THE ROAD. ONCE DISABLED ALONG SIDE THE ROAD THE WEATHER BEGAN TO DETERIORATE TO NEAR WHITE OUT CONDITIONS, THANKFULLY ANOTHER DRIVER PULLED UP BEHIND ME ABOUT 50 YARDS BACK AND USED HIS FLASHERS TO WARN ON COMING DRIVERS. AFTER THE TRUCK COOLED A BIT...

5 EXHAUST BOLTS HAVE BROKEN OFF ON MY 6.0 LITER CHEVY ENGINE. 3 ON THE DRIVER'S SIDE AND 2 ON THE PASSENGER SIDE. THIS IS A COMMON PROBLEM WITH THIS ENGINE THAT CHEVY WILL NOT STAND BEHIND. THE LOCAL DEALER QUOTED ME $2,000 TO FIX THE PROBLEM. *TR
