Some pics
Ready to set off.
Today went from this...
To this...
Offending servo vacuum pipe clip (One below the jubilee clip)
Once head was removed
Thinking about it. I think what we mistook through the bore scope for being watermarks on the bore were infact traffic film remover (TFR) stains from when the block was cleaned. I remember seeing them when honing the bores. They are just visable on other cylinders too but more so on #3 for some reason.
Will crack on again tomorrow no doubt! lol
Cheers!
