Re: LS7 Rocker Arms - Issue??
What's "silly" is continuing to use rocker arms they know are prone to failure, and have been since the C5. This is not a problem new to the C6. Replacing all the rockers will not fix the issue. Since the new rockers are the same, they too are subject to failure.
Apparently, it's the intake rocker arm that fails most often and rarely the exhaust valve. This is possibly exacerbated by the LS7's offset rocker arm design on the intake side.
Even if they did replace them all, there are often 20-30 needle bearings still in the engine. Therefore, when you find even one during a routine oil change call GM and tell them you want a flatbed to take your car to a dealer. After all, they can't prove a recently discovered needle bearing or bearings are from the previously failed rocker until they inspect all the rocker arms.
