Consumer Description

I HAD A FRIEND WHO HAD AN ENGINE FAILURE ON THIS SAME ENGINE DUE TO A FAILED EXHAUST VALVE. THE VALVE GUIDES WERE EXTREMELY WORN ON HIS CAR CAUSING THE VALVE FAILURE. DUE TO HIS FAILURE AND MANY OTHERS LIKE IT, I REMOVED MY HEADS AND INSPECTED. SURE ENOUGH, THEY WERE SIGNIFICANTLY BEYOND GENERAL MOTORS PUBLISHED TOLERANCES AND REQUIRED MACHINING TO REPAIR. THIS WAS AT SIGNIFICANT COST TO ME AND OUT OF POCKET. GM KNOWS OF THIS ISSUE AND REFUSES TO PARTICIPATE IN REPAIR COSTS FOR CARS OUT OF WARRANTY EVEN THOUGH IT'S A DESIGN FLAW AND SAFETY CONCERN. IF AND WHEN THE VALVE CATASTROPHICALLY FAILS, THE ENGINE WILL HAVE A COMPLETE SHUT DOWN, LARGE AMOUNTS OF SMOKE OUT THE EXHAUST CLOUDING THE OTHER DRIVERS VISION, AND HAS THE POSSIBILITY OF LEAVING OIL SLICKS ON THE ROAD SURFACE. *TR
