Wow! Not sure if they would be any use though? I mean, how much can you take off the crank before the hard surface has gone?

Pretty good. Was this after a big-end failure? Check the con-rod(s) if so, it might be ovalled...

It was after a BEF and both the rod and piston are F'd, i have spare, i'm going to have to replace the rings which i would do anyway and they are 16 incs of vat each not bad i thought... The crank should last longer than it did before as i was a belt failiure at 50k miles that did it...
