NHTSA Complaint #11447036 — 2013 CHEVROLET CORVETTE

.The internet (Youtube and Corvette Forum) is full of horror stories about the engine valves breaking and dropping into the engine causing a catastrophic engine failure without warning. I was paranoid about driving the car for fear of an engine failure and averting an accident. After reading a plethora of horror stories about numerous LS7, 427 engine failures I felt anxious about driving my car and wanted to fix my engine ASAP and not a moment to soon!!!! I took my car to a shop to determine the condition of the valves and one intake had extensive play in the valve guide - .012" wobble from side to side vs a factory spec of .003". They didn’t check the other head but assuming the worse. I just have my heads refurbed at with only 6k miles on my vehicle. This resulted in me spending $5,350 dollar to remedy the defect before the engine failed and potentially causing an accident. ........this problem seems to be a manufactory defect potentially common to all 427/LS7s built between 2006 and 2013!!!!!
