Calling this a liner failure,
but we need confirmation.
Description is garbled.
Bridge cannot shut down one cylinder.
The engine must be totally shut down
in order to cut fuel to a single piston.
Moreover, the cooling system is not isolated by cylinders.
If it was a liner failure,
they would have to remove the piston and liner,
which is a 4 to 10 hour job,
and isolate everything before restarting engine.
