2000 Chevrolet Silverado Engine Problems

HELLO, I WAS DRIVING AND ALL OF ALL SUDDEN THE CAR WAS NOT ABLE TO MAKE ANOTHER CHANGE AND I STOPPED AND CHECKED THE FRON OF MY CAR AND NOTICE SOMETHING WAS LEAKING FROM THE ENGINE, AND HAD BEEN TOLD THAT IF THE ENGINE HOT DAMAGE I WOULD HAVE TO HAVE A NEW ONE PUT IN. I COULD ONLY SPPED UP TO 35 MPH

ON THE EXHAUST MANIFOLD, THE BOLTS BREAK OFF AT THE HEAD OF THE BOLT WHETHER THE VEHICLE IS IN MOTION OR NOT. SOMETIMES THE BOLTS BREAK OFF FLUSH WITH THE MANIFOLD AND SOMETIMES THEY BREAK OFF FLUSH WITH THE HEAD. I PERSONALLY HAVE HAD 6 OUT OF THE 12 BOLTS ON MY ENGINE BREAK OFF. THE FIX IS TO DRILL OUT THE REMAINING PIECE OF BOLT (THREADED PART) AND THEN USE A BOLT EXTRACTOR TO REMOVE THE REMAINING PIECE OF BOLT THAT IS STILL SEIZED IN THE HEAD. WELL, THE MOST COMMON BOLT TO BREAK OFF OUT OF THE 12 MANIFOLD BOLTS IS THE ONE DIRECTLY IN FRONT OF THE DRIVERS POSITION. UNFORTUNATELY, THAT IS THE HARDEST BOLT TO REMOVE BECAUSE OF IT'S LOCATION. MOST SHOPS I'VE BEEN TO SAY THAT THE TICKING SOUND THAT YOU HEAR ONCE THIS BOLT BREAKS OFF IS A LOOSE LIFTER. THAT IS INCORRECT! THE TICKING SOUND IS ACTUALLY AN EXHAUST LEAK STEMMING FROM, MOST LIKELY, THE BROKEN BOLT DIRECTLY IN FRONT OF THE DRIVER. THE SOUND GOES AWAY ONCE THE ENGINE WARMS UP BECAUSE OF THE METAL EXPANDING WITH THE TEMPERATURE INCREASE. I HAD 3 MECHANICS UNDER THE HOOD OF MY TRUCK FOR ALMOST 9 HOURS TRYING TO REMOVE THE 6 BOLTS THAT HAD BROKEN ON MY ENGINE. THEY HAD BROKEN EVERY DRILL BIT IN THEIR SHOP (THE SHOP IS A 14 LIFT, 16 BAY SHOP) THAT COULD POSSIBLY BE USED TO DRILL A HOLE FOR THE EXTRACTOR JUST TRYING TO GET A HOLE FOR THE EXTRACTOR TO FIT IN AND THEN THE BOLT EXTRACTOR BROKE OFF IN THE LAST BOLT WHICH HAPPENED TO BE THE ONE DIRECTLY IN FRONT OF THE DRIVER. THEY HAD THE CROSS MEMBER REMOVED AND WERE PREPARING TO DROP MY ENGINE WHEN I TOLD THEM TO JUST STOP THERE. I COULDN'T AFFORD ANY MORE OF A FIX SINCE I WAS $1,800 DEEP INTO THIS ONE DAY AT THE SHOP AS IT WAS. THIS IS SUCH A COMMON PROBLEM THAT THERE ARE AFTERMARKET CONTRAPTIONS TO BOLT ON AND CINCH THE MANIFOLD DOWN WITH ANOTHER BOLT. THAT ISN'T THE RIGHT THING TO DO. THERE SHOULD BE A RECALL AND I SHOULD GET REIMBURSED!

HAD TO DISCONNECT THE ANTI LOCK BRAKE SO I COULD STOP. WHEN DRIVING SLOW AND PRESSING ON THE BRAKE PEDAL, THE PEDAL IS SOLID AND DOES NOT MOVE. VERY DANGEROUS. CANNOT STOP THE VEHICLE AT ALL. BRAKE LINES ROTTED OUT. HAS TO REPLACE. TRANSMISSION LINES ROTTED OUT. HAD TO REPLACE. TRANSMISSION OIL COOLER ROTTED OUT. HAD TO REPLACE. FUEL LINES ARE ROTTING OUT. NOT REPLACED YET. DRIVE SHAFT IS QUESTIONABLE. SEVERELY RUSTED. REAR BACKING PLATES ROTTED OFF, NO MORE PARKING - EMERGENCY BRAKE. CHECK ENGINE LIGHT WILL NOT GO OUT. REPLACED CATALYTIC CONVERTER MANY TIMES WITH NO RESULTS. ENGINE LEAKS OIL. LOOSING COOLANT, POSSIBLE BURNING IT. FUEL MILEAGE IS TERRIBLE. BODY RUSTED OUT. ROCKER PANELS ARE GONE. CAB CORNERS ARE GONE. REAR BUMPER IS GONE. PUTTING THE SPARE TIRE UNDERNEATH IS A STUPID IDEA. THE COST TO REPLACE THESE PARTS IS TOO EXPENSIVE. FOR WHAT THESE VEHICLES COST NEW ALL OF THESE PARTS SHOULD BE MADE OUT OF STAINLESS STEEL OR USE PLASTIC FOR THE FUEL LINES AND BRAKE LINES. THE CHECK ENGINE LIGHT BEING RELATED TO A POLLUTION CONTROL DEVICE SHOULD BE ENTIRE COVERED BY THE MANUFACTURER. THESE PARTS AND WHATEVER IS UPSTREAM THAT CAUSED THE POLLUTION CONTROL PART TO FAIL SHOULD BE COVERED BY THE MANUFACTURER IN PERPETUITY. ANTI LOCK BRAKES SHOULD BE REMOVED FROM ALL CARS. THE PARTS ARE TOO EXPENSIVE TO REPLACE. THE COST SHOULD NOT BE ON THE SHOULDERS OF THE CAR OWNER. *TR

MY TRUCK HAS THE BAD GM CASTECH CYLINDER HEADS THAT LEAK COOLANT INTO THE OIL. GM KNOWS ABOUT THIS PROBLEM VIA GM TSB. DEALER AND MFG. REFUSED TO DO ANYTHING. I FEEL THIS IS NOT A MECHANICAL WEAR ISSUE. IT IS BAD HEADS FROM THE MANUFACTURER. GM SHOULD BE FORCED TO ACKNOWLEDGE THIS ISSUE AND RECALL THE AFFECTED VEHICLE. *TR

EXHAUST MANIFOLD BOLTS BROKE OFF RESULTING IN PINGING NOISE. MY MECHANIC VERIFIED THE BROKEN BOLTS AND TOLD ME THIS COULD LEAD TO OTHER MORE SERIOUS PROBLEMS INCLUDING POSSIBLE FIRE. HE ALSO SUGGESTED I SHOULD CONTACT A GM DEALER TO SEE IF THERE WAS A RECALL FOR THIS PROBLEM. I HAVE BEEN DRIVING FOR MORE THAN 50 YEARS AND I HAVE NEVER HAD EXHAUST MANIFOLD BOLTS JUST BREAK OFF. *TR

DURING A UTAH STATE SAFETY INSPECTION LAST YEAR IT WAS FOUND THAT 3 OF THE 12 EXHAUST MANIFOLD BOLTS WERE BROKEN ON MY 6.0L ENGINE. THE BOLT HEADS WERE COMPLETELY BROKEN OFF/MISSING. THE BROKEN BOLTS ALLOW THE EXHAUST MANIFOLDS TO LEAK CAUSING PROBLEMS WITH EMISSIONS. IF LEFT UNDETECTED THIS PROBLEM CAN CAUSE THE CATALYTIC CONVERTER TO FAIL. JUST TO HAVE THE BOLTS REPAIRED IS A VERY EXPENSIVE >$500 REPAIR THAT COULD HAVE BEEN AVERTED BY HAVING THESE FAULTY BOLTS CHANGED OUT EARLY ON. ONCE THE BOLTS ARE BROKEN THEY HAVE TO BE EXTRACTED WHICH IS VERY DIFFICULT DUE TO THE THERMAL DEFORMATION AND CORROSION. TWO OF THE BOLTS WERE IN THE REAR MOST HOLES WHICH HAVE VERY LIMITED ACCESS. I HAVE NOT RECEIVED ANY NOTICES FROM THE MANUFACTURER IN REGARDS TO THIS PROBLEM. I HAVE OWNED THIS TRUCK SINCE IT WAS NEW. I WOULD LIKE TO REQUEST A RECALL FROM THE MANUFACTURER DUE TO THE FACT THAT IT CAUSES EMISSIONS PROBLEMS AND INCREASES POLLUTION. IF YOU CONSIDER HOW MANY OF THESE TRUCKS, TAHOES, AND SUBURBANS HAVE BEEN ON THE ROAD SINCE 1999, THE INCREASE IN POLLUTION IS CONSIDERABLE. *TR
