Thanks Ross.
I have the first problem today, to date everything on the engine has been coming up good. The engine shop were honing the cylider bores and they were looking Ok, as in the First picture. As mentioned in the first picture the cylinder liners are floating that is they move around quite easily. This is why a block plate MUST be fitted prior to doing any honing or boring of the cylinder bores. The block plate that the engine shop used is in picture 2. The problem can be seen in this picture in the third cylinder on the top bank. It appears as if water has been resting in this piston and has corroded the bore and the honing was unable to remove it. The engine shop said that it possibly would not effect the running of the engine and when I ran my finger over it you could not feel any variation, he advised that it could possibly allow some oil to get past and could possibly smoke, needless to say I will be ordering a new cylinder liner. I have given a closeup of the damaged cylinder bore in the third picture. Investigating where the water possible came from, the cylinder heads have pressure tested Ok still looking. Will probalby take another month to get the cylinder liner so that will slow things up again
Plenty of other things to keep me busy though
