I'm fairly sure the damage has occurred since a PO had some engine work done about a couple of thousand miles and ten years ago (I've only taken it round the block so far). My priority is to preserve the crankcase.
Thanks Stuart and Dave, I'll give Tony a ring.
Jon, Chris Gould's guide says the front camshaft journal is larger than normal, hence the camshaft pinion has a larger centre hole. Apparently the timing gears were steel rather than iron. (A Guide to the Austin '65' and Nippy, CSW Gould, p36)
eta beaten to this by Alan and David - thanks.
With an original sports engine I'd be calling Dave Dye to get a new steel set. That fracture surface doesn't look like steel.
You really don't want them breaking
