2008 Chevrolet Corvette

I WAS CONCERNED ABOUT EXCESSIVE VALVE TRAIN NOISE AND AFTER READING SEVERAL CORVETTE FORUM THREADS ABOUT IMPROPERLY MACHINED HEADS BY GM'S SUPPLIER LINAMAR, AND THAT NUMEROUS VEHICLES HAVE HAD VALVES DROP AND RUIN THE ENGINES, LOOSING A VALVE WHILE DRIVING WILL RESULT IN LOSS OF POWER ASSIST FOR STEERING AND BREAKING WHILE ON THE ROAD . I TOOK MY CAR WITH 13500 MILES ON IT TO A CORVETTE SPECIALTY SHOP TO HAVE MY VALVE GUIDE CLEARANCE TESTED. I HAD (8) EXHAUST VALVE GUIDE AND (3) INTAKE VALVE GUIDES OUTSIDE OF SERVICE SPECIFICATIONS, AND A COMBINATION OF (5) OTHER INTAKE VALVE GUIDES AT OR NEAR THE MAXIMUM OUTSIDE OF SERVICE SPECIFICATIONS. THE CAR IS BEING REPAIRED WITH PROPER RE-MACHINING OF THE HEADS TO MAKE THE VALVE GUIDES CONCENTRIC, NEW INTAKE AND EXHAUST VALVE GUIDES INSTALLED, AS WELL AS NEW SEALS, VALVES, SPRINGS, ETC. I CAN PROVIDE DATA ON THE FAILED GUIDES FOR DOCUMENTATION 88% OF THE CORVETTE FORUM MEMBERS WHO HAVE HAD THEIR CYLINDER HEADS TESTED FOR EXCESSIVE VALVE GUIDE WEAR, WERE OUT OF SERVICE SPECIFICATIONS. SOURCE: HTTP://WWW.CORVETTEFORUM.COM/FORUMS/...-REGISTRY.HTML GM NEEDS TO ISSUE A RECALL ON THIS ISSUE, THERE HAVE BEEN NUMEROUS ENGINE FAILURES AS A RESULT OF A DROPPED VALVE INTO A CYLINDER WHICH CAN CAUSE ACCIDENTS AND FIRES. GM IS VERY AWARE OF THIS ISSUE, BUT REFUSES TO DO ANYTHING ABOUT THIS HUGE SAFETY RISK TO DRIVERS, PASSENGERS, AND NEARBY VEHICLES IF THE ENGINE FAILS GOING DOWN THE ROAD. *TR

I HAVE WRITTEN BEFORE ON THIS PROBLEM. DO YOU FOLKS EVER ACKNOWLEDGE RECEIPT OF A COMPLAINT. THE CAR HAS A STRONG SMELL OF GASOLINE UNTIL THE TANK IS HALF EMPTY. THIS IS A LARGE PROBLEM AFFECTING MANY CORVETTE OWNERS AND THE FUMES ARE VERY BAD INSIDE AND OUTSIDE THE CAR. THERE WAS NO DATE OF INCIDENT AND IT DID NOT ARISE FROM ANY ACCIDENT. *TR

DUE TO A CRACKED FITTING ON TOP OF THE DRIVERS SIDE FUEL PUMP, FUEL IS SPRAYED OUT AND SOME POOLS ON TOP OF THE TANK. IN THE MORNING THERE IS A STRONG SMELL OF FUEL INSIDE AND OUTSIDE OF THE CAR. THIS WOULD NOT NORMALLY BE AN ISSUE ON MOST CARS, BUT BECAUSE THE FUEL TANKS ARE SO HARD TO REMOVE AND EXPENSIVE TO REPAIR THE FUEL PUMP IS A $2,000 OR MORE REPAIR BECAUSE TRANSMISSION MUST BE REMOVED FROM THE CAR TO GET TO THE FUEL PUMP. ON A RELATED NOTE GM HAS A REALLY BAD PROBLEM WITH THE FUEL LEVEL SENSORS GOING BAD AT LOW MILEAGE. THIS SENDS AN ERROR CODE AND A OWNER CANNOT PASS A BI ANNUAL SMOG CHECK UNTIL THEY PAY THE LARGE SUM OF MONEY TO GET THE FUEL LEVEL SENSORS REPLACED, ONCE AGAIN HAVING TO DROP THE TRANSMISSION TO DROP THE FUEL TANK TO REPLACE A FIFTY DOLLAR PART COST AROUND TWO THOUSAND DOLLARS. SO MY COMPLAINT IS THAT THE EPA OR FEDERAL AND STATE SMOG LAWS AND THE ERROR CODE, MAKE THE OWNER DO THE REPAIR, TO THE FUEL LEVEL SENSOR ALTHOUGH IT REALLY DOES NOT AFFECT THE EMISSIONS OF THE ENGINE, WHILE IT IS PERFECTLY FINE TO DRIVE AROUND WITH GAS SPILLING OUT WHILE DRIVING. THIS IS A SERIOUS ENVIRONMENTAL ISSUE ON TOP OF THE OBVIOUS SAFETY ISSUE THAT GM DOES NOT WANT TO BE ACCOUNTABLE FOR... THIS NEEDS TO BE FIXED FOR ALL CORVETTE WITH THE LOW MILEAGE LEAKING FUEL PUMP AND THE OWNERS SHOULD NOT BE THE ONES AT FAULT... *TR
