You will need to remove the following.

Air Filter Assembly
Turbo Intercooler Assembly
Engine Cover (to expose the IP fuel lines to injectors)
Injection Pump high pressure lines (be careful when removing to avoid damaging the radiator fins)

after removing those, you can now remove the intake manifold

remove the EGR
remove heater connections

the intake manifold have bolts above and below, you just need a mirror to see the bolts below or use your hand to locate them

now you can remove and clean your intake manifold..

remember to bleed the high pressure fuel lines!!

ask someone to crank the engine (do not fully tighten the fittings at the injector!!) when the engine cranks, fuel will leak on the injector fittings, until the engine idles, slowly tighten each fitting until there are no leaks visible..
