Hi R4N.

When the car was run with the expansion tank cap on it sounded like a pressure build up, when the cap was removed it sounded like a normal cosworth.

Once the head was removed on number 4 where the gasket sists there was a indentation causing water to be passing hence why it kept spilling the antifreeze out.

Regarding the Bill its not an ideal time for me to be spalshing the cash about but i thought as i had it in storage a minor service would suffice, how wrong was i.
But will be worth it when i get in it and drive it....
