You will need a socket set and the rocker cover bolts may... be star keys can't remember. Also feeler guages... A torque wrench would be useful, but not essential.

Looking at this picture, you will just have remove the right banana and you can get at the rocker cover. You may also need to disconnect the EGR throttle rod, EGR pipe and support bracket. (in the picture, EGR ROD has alreayd been removed, normally goes from top of fuel pump across top of engine to EGR - EGR is that UFO shaped thing)
(to remove the other side it looks like the injector pipes get in the way..., can't see why it needs to come off anyway)
There is a metal gasket between the bananas so be careful when you split them. There is also a gasket between the manifold and cylinder head. If you are careful you should be able to reuse it. Some gasket paper or some RTV silicone may be good forward thinking.
With the rockers exposed, turn the engine on the crank pulley and follow these settings:

Torque settings are: 6-8 NM or 4-6 lbf ft (hand tight)

When putting the bana inlet manafold back:
Torque settings are: 20-25 NM or 14-18 lbf ft (till it bites, then a TINY bit)
