GM will replace the failed pump with the exact same one. For those that build engines, they can confirm most of this is from the lack of proper de-burring the pump during assembly from the supplier of them. Rare to see a Melling or a OEM pump that has been blueprinted have the bypass valve stick and a subsequent failure. This is for ALL LS based GM vehicles, truck versions, Corvettes, etc. And no, a proper catchcan system is impossible to be related to an issue like this that has been a problem with the LS engine since 1997 when the first LS1 was released.
