Re: The problem...
I agree with those who have said it'll corrode less if full of water (even without an inhibitor) than if wet and full of air. Basically there is less oxygen in the water than there will be in the air that replaces it when drained down.
It is very difficult to get an antifreeze mixture distributed throughout the engine but it obviously depeds on the actual engine. The best bet is to drain it all down (after flushing through with fresh water), gearbox cooler and all the pipework included, then start it up on an antifreeze mixture and run it just for long enough to fill the system.
