Ian, I feel you pain I really do! I felt exactly the same when mine was diagnosed just over a year ago, absolutely gutted, and I am sure you are going through all the same emotions.
Do you have pics from the borescope examination? Maybe worth comparing with mine. I had scoring on Cylinder 4 only when diagnosed, no symptoms at all at the time, it took about 6 months for them to emerge, initially a more sooty left tip followed by the ticking noise which go progressively worse over the next few months. When the engine was taken apart, cylinder 4 was heavily scored with cylinder 6 showing light scoring,
As others have said, it could well be years before the engine needs to be addressed. For me, it was always at the back of my mind, so I can understand why others say not to check the bores and wait for it to happen if it ever does. In saying that, I had plenty time to consider the options and sort out finances to pay for the rebuild.
