when I tried it the engine just went bang and then it was locked and wouldn't rotate.

car was still moving and I could fell it braking. which was the clutch slipping as the engine was locked but the wheels was turning.

My friends 1098 mini still drove with a broken crank.
Broke at the main bearing journal at flywheel end. Lots of knocking and rumbling noises
