So probably easier if Dave, Dec or someone with a better knowledge explains it but basically the end of one of the sparks plugs broke off and was crushed by the piston causing it to break up , slight damage to piston and head but easily fixed by the machine shop, so all cleaned up and put back together i should be back motoring by Monday week

Failure was broken plug tip.
Head damage will clean up. All valves to be removed, checked. replace any needed and reseated.
Piston damaged will not be used again. Replacement required.
Very luck no cylinder wall marks or damage.
No pick up on bearings.
So be fresh recon. New big end and mains, new oil pump, new piston rings, all gaskets, all seals, new timing belt
good to go.
as per normal can follow progress on our facebook page
