Above: Metalock repair on crankcase door - port & starboard sides
The crankshaft has suffered terrible damage due to overheating and some journals are blue and hard due to excessive heat caused by the lack of lubrication. Does this mean a new crankshaft?

Metalock UK have recently salvaged 6 main engine blocks following catastrophic failure using a combination of our emergency services. All engines have been passed by class to return to service.
