Classic.. The engine was ran with a bad lifter for way too long.. Excess valve lash really beats on the lifter carrier and creates this issue. In 2012 we saw 30 cases of this, more than any other time.

Thats repairable.. Its a better case scenario failure, BUT now your challenge is to remove the residual debris from the engine before it takes out more internals AFTER the rebuild. I hope the shop has a powerful ultrasonic cleaner, its the only way to remove the debris from the passageways within the engine and internals.
