I found the best way of all. Today I went to work with the cylinders and gave them to the mechanical fitters. 10 minutes later they brought all the parts all ready for rebuilt (except the cylinders).
So tomorrow ill post the cylinders off for coating and then play the waiting game.
Cheers All.
*Just a quick question. Has anyone tried electrosil? I'm just getting the old nikasil but was wondering if it's actually worth the extra cash.
