Write everything down everytime u do it, and let us know how u go. U can keep winding and winding the engine over until it, if at all comes up to spec, but it's good to try both short wind and long wind if your not getting a clear result.

I didn't read your original post properly, are u positive the smoke is white/grey? Is there any tinge of blue in there?
Thanks very much Shaun.
We just completed the test. Cylinders 1, 2, 3, 5, 6 tested from 420-470. Cylinder 4 tested at 210 dry. We tested the 4th a few times wet, starting with a thin oil, than a thicker oil, and the highest it went was 230. We wound it over 3 revolutions for each one.
No mate, it doesn't seem to have any blue tinge to it at all.

Now with that test done, a top end rebuild is in order. Is it possible to buy just a top end rebuild kit?
