Hi Richard, just about everything, re ground crank new mains and big ends, new pistons and liners ,valve seats recut new valve guides and valves, recon injector pump and injectors, new timing chain, rebuilt starter nos dynamo and water pump, once you start where do you stop, it was in a very poor state when first dismantled, all the white metal bearings were starting to break up, looked like a jigsaw with pieces missing, plus I won't be parting with it any time soon and hopefully will be finished for Normandy next year so it needs to be right.
