We've made the decision to pull the head off now and replace it with another one straight away, we arent even going to strip it down to see if its done guides etc in as its wasted time.

So fingers crossed the pistons have survived it in tact, as thats the only thing we are stuffed for as no chance of getting hold of another engine and fitting it within the next 8 hours.

If the pistons are in one piece still and havent taken a hard enough hit to crush the ring lands down it will all go back together in time hopefully.

Rob is spannering away feverishly as we speak, hopefully its just a case of putting a new head on and getting the gearbox back on and it will be fine.
