Yeah had a good day, was a good laugh going round the track. The journey home was uneventful so we thought we would pop into essex off road, ended up popping the radiator bleed cap, managed to find another one and then snapped the top bleed cap as I wa putting it back on after refilling the coolant... ended up with a bolt and araldite blanking off what was left of the cap... worked though and got me home! Im pretty sure theres no engine damage as it drove home spot on but will be bringing my block tester home tonight to double check!
Overall a long, eventful but fun day... couldn't have asked for nicer weather for it...
