Everything should stay in place if you're gentle when removing. It's the stupid vacuum pipe thing that clips into the pollen filter tray that gets in the way. Makes it tricky as you need to lift the manifold up, and then bring it towards you underneath those pipes..

The 8 bolts are captive, but the nuts aren't.
Also as a tip, remove the clipped in rubber bit the strut brace passes through, as this will give you a few mms more clearance on the manifold removal.

Soak the manifold in a deep bath of warm water and 1kg of Caustic soda crystals overnight to remove all the oil and carbon.

Wash through thoroughly with water afterwards and it will be like new inside. (Very messy though, and wear gloves!!)
