Hi,
It really depends what the problem is... If something broke off the flywheel and damaged the big end mounting, then that would be the end of the crank shaft... That means a new short motor/engine... It is probably cheaper to replace the engine than to replace the c4rank shaft... Also, they may want to send the engine to germany for inspection to see if there is some kind of flaw or cause for the failure...
