It's going ok, however I'm beginning to think that the less you know the better!

I've got the head off waiting to send it away on monday to get ground and pressure tested. It looks like the gasket was slowly disintegrating between the water gallery on the exhaust side of cylinder 1 and the outside of the block. There is no signs of water in oil or vice versa which is a good thing in terms of preserving the bottom end.

BUT I've discovered a light scoring mark in cylinder number 4 which could mean a few things; cracked ring, cracked ring land or cracked piston skirt. Or what I'm hoping is that something foreign went through the motor and left it's mark!

Either way it's not getting fixed as I've got 3 weeks before racing at PI and no chance of a bottom end reco before then. Atleast I know now to plan for a full reco in the near future.

On a positive note I found I stuck an incorrect exhaust gasket on it when I last had the turbo off which was covering about 1/3 of the port
That will atleast be worth a few hp when I put the correct gasket on.
