Tuesday 7th May 2013, Coonabarabran.
Here is another report on the mechanical situation. It appears that there is enough damage to the head and associated parts to require a new complete head replacement, and fortunately, at this stage, there does not seem to be any damage with the lower portion of the engine, but all will be ultimately revealed on completion of head replacement. This hopefully being the case, we will still be up for a substantial repair bill, but nowhere near as much as if there was lower engine damage. We will be here in Coonabarabran until at least Saturday, repairs are dependent on parts delivery, and then attaining the finances in time will ultimately dictate our departure date. We have accepted now that we will just have to grin and bear the cold nights we are experiencing while here.
