As we came through Coonabarabran this morning, the navigator with good ears said 'there's a new noise'. Hmm thinks me. When I used the exhaust brake towards the start of the Pilliga scrub, same noise. Found a rest area to diagnose problem. Finally found that a flange between the exhaust manifold and (I think) the inlet manifold heat exchanger had lost a couple of bolts and was loose. The only way to reach it was from inside the mhome at the rear of the engine. Mr Repco at Narrarbri had some bolts for me, and I bolted it all together on the side of the road.
When we crossed into QLD the police on duty just wanted to see my border pass.

All good . Now we are parked at the Aratula pub because it is too late to make it home.
