Second Blueprint 408 issues

The shop did all the inspections to rule out the noise coming from somewhere else. Then they went one by one disconnecting the spark plug wires and found the noise stopped( or significantly decreased) when the #2 spark plug wire was removed. I went by and pulled the dip stick, lots of metal shavings, way more than before. At this point everything is pointing to rod bearing failure on #2 cylinder. I told the shop to pull the motor and remove the pan.
