Actually I dont think those dust storms care much if your engine is in bits or not. In Kuwait I would open a sealed, never used jar of peanut butter or mayo and there would be a dust layer under the sealed lid! After a dust storm it is everywhere!
I lived in Sydney for a year way back and loved it. I have been looking for ways to get back there to work ever since. I got my masters at Uni of Wollongong, they have a learning center in Sydney right off of Hyde Park. I lived off Oxford and Flinders street. what a great time! I used to take the ferry to Watsons Bay, get some fish and chips and walk the cliff walk back to town. AWESOME!!! My wife is tired of hearing how great it is and wants to move the family there.
