The symptoms of a 3 bearing crank failure?

[fatcatvera]

I’ve managed to get the engine out of the car and mostly apart this evening. The crank has failed across the web to the rear of the centre main bearing. Very similar to the image that Rauiridh has shared. It hasn’t quite cracked the whole way across the web yet - there’s still about 10mm of joined metal. I can imagine the mess it would have made of the crankcase if it had failed completely.

I’ll upload some images when I’m at a computer (I’m writing this from my phone).

Chris KC - it is indeed a small world! My brother told me he’s had a chat with you - have a you got a spare 3 bearing crank?!
