Blumby - yes I did use your advice - sorry I should have mentioned it - I tried the two nut approach - and it worked really well as far a getting a good solid grip on the stud was concerned - it gripped it really solidly. In fact it gripped so solidly it got to the point where I felt the torsional force I was applying to the stud was just about sufficient to snap it - hence I gave up and decided to apply more lubrication and more time. But the two nut trick worked really well - as well as my Stud Extractors anyway.
The piston really has moved in the bore - it is only a small amount, but I can definitely see more of the ports, so it has genuinely moved in the bore a small amount.
I agree - I have received excellent advice for everyone - and I will continue using everyone's advice - lubrication, time, judicious use of mallet and wood, and patience.
As I said previously, I will need to head out of Sydney for 6 months in 5 weeks time - and if necessary, I am quite prepared to leave it soaking for the 6 months I am away.
