Cracked 'A' Crankcase - Large Idler Boss

Close examination of my stripped 'A' Comet Special cases reveals a crack along the top of the large idler boss disappearing into the oil-hole. :mad: It will be a real pain trying to get down inside there with any kind of welding torch, so I guess my other options are:

1. Just leave it alone on the basis it has probably stress-relieved itself - and hope it doesn't cause a blow-up in due course. :eek:

2. Bore the boss out and fit a thick bronze top-hat bush (but that might get tricky trying to maintain correct timing gear meshing...). :confused:

Has anyone else encountered this problem, if so, how did they fix it?
