I used the cut out method to get the original stuffed mount out. The problem was trying to press the new one with water as a lubricant as everyone suggested got stuck half in, half out. I didn't want to then cut out a new mount that Patrick had sent from US to Sydney. Eventually I used the wooden blocks, lowered the car to use the weight as a press and then an engineers hammer to add some vibration.

Now I'm in search of a rubber lubricant. BMW Aust couldn't suggest anything here that would work.
