Threre is 6 bolts, if you remove the top part of the inlet manifold it will be a bit easier to undo them, I absolutely soaked mine with wd40 and they came off ok, you need to be carefull as they can sheer off then u are buggered, dont worry about the flexy bit, use wire wool to try and clean the faces, the wd40 will help clean them with the wire wool, I used some gun gum on the gasket to get a good seal.
