I got an after lunch call from the Orange Toyo dealer, expecting to learn of the results of the promised compression test, only to be told that they can't actually do the test till Thursday afternoon. They said that they could not say when any repair would start or finish, that the engine was probably buggered through dust damage and that it would probably take several weeks to get parts, quite possibly from Japan.
When the dummy stopped bouncing around the inside of the caravan, I called up Mechanic B. He's the one with a RH turbo on the shelf and a crate engine on the floor. The engine will have to come out and it looks like about $5K to replace the turbo and do a prior compression test. It will probably cost a bit more than that because of the age of the vehicle and all of the extras under the bonnet. We booked a tilt tray to pick the vehicle up from Toyota tomorrow morning.
I then called up my own mechanic in Sydney, who has serviced the vehicle every 5,000km in the four years or so that I have owned it. He said in no way was there any dust damage to the motor. It compression tested perfect when I bought it.
So, with a bit of luck, it will be a simple turbo change, inspection of other turbo and overall check of the engine on the shop floor. There is a very tiny leak in the steering rack, which is only going to get worse, and it might be a good time to get that attended to as well.
Nothing you can't fix with money. The NRMA Premium Service is paying for our car rental for the time being up to $700 plus $700 for accommodation. I'll ask tomorrow if we can roll all of that into car hire.
