Guide to remove upper inlet manifold

[bad_lad]

Hi, i have a 172 CUP and after starting the car from warm it started making a hideous loud noise, a noise like sum1 had removed the exhaust manifold, anyway further investigation reveals that no.1 spark plug had been forced out of the head, have no idea why this has happened and hope it had just cum loose and that there maybe some threads left to replace it. Does anyone have a guide on how to remove the upper inlet manifold?, any help would be greatly appreciated.

Undo all the 10 mm bolts on the plenum front and 2 at the back. Unplug the sensors and thats about it. Kind of all explains its self as you tackle it
