Tools need:
-12mm sockets, 10mm sockets, 14mm sockets, 8mm sockets, deep and shallow. Both in 3/8 drive and 1/4 drive.
- Vise grips, the ones that lock like needle nose
-Ratchets, 3/8 and 1/4 drives( flex-head ratchet helps )
-universal sockets set /or universal joint
-toque wrench
-1/4 socket and 5/16 socket/8mm for new clamps
-PB Blaster.
-1/4 and 3/8 extensions
-screwdrivers and picks
-magnetic
-Floor Jack and jackstands

Parts
-Intake Manifold set





Begin by running the car, remove the fuel pump relay(green) to release the fuel pressure.


Begin by disconecting the negative battery cable with 10mm socket/wrench
Remove the fuel injector rail.

First remove 2 bolts (10mm) from the bracket and both hoses, and label the FUEL PRESSURE REG vac hose

Then Remove all cover/panel with 10mm socket and then drain anti-freeze by removing the plastic bolt with phillips srewdriver.

Then remove the passenger wheel by removing the four 21mm nuts with a
impact wrench/lug wrench. Next remove the black plastic panel cover (use 10mm socket).

Yeah, I thought these would get moved to the FAQ/Stickied??
Sure would be so they don't get lost in the new posts, and maybe people will find them easier there without having to ask without looking first but baby steps :)

Remove the power steering pump, there is a black bracket with the pump with two 14mm bolts that go to the block,

There is a bracket from the Power Steering pump to the Plenum, with a 12mm boly, easy done with u-jont and socket

Remove the 12mm bolt, that holds the pump on the upper bracket, it is pain in the ass, but it is easy if
you have a 12mm ratching wrench

Unplug all the wiring to the intake manifold, there one from the top to IAVC, one with 8 -pin connector. Remove the red plug to coolent sensor, and all wiring to plenum and to intake manifold, label it all,

Remove the oil filter adpater(where the oil filters screws) with 12mm socket with u-joint socket( four bolts)

Remove the brackets: the one by the Power Steering Pump with 12mm socket with ratchet, go by the wheelwell with u-joint

(if you forgot to remove it)
and the one by the starter, 4 12mm bolts, 2 are the throttle bodyand the other 2 are by the starter

Remove all hoses, wires, and label everthing.


Now take break, your choice

Now loosen, but dont remove yet the 3 bolts and the 2 nuts, from the intake manifold to the collector, and push it, allow it drop so you have room to remove the intake manifold bolts to head. those are PITA, you have to be creative
to remove them, be like monkey. Put some padding over the valve cover so you will be
relaxed.

Now remove the EGR pipe with ajustable wrench( use pipe over it)
(it has a big nut, use alot of PB blaster on it


Use a 12mm flare nut wrench and remove the line: (Tip use alot of PB blaster )



After that work it should look like this:
This will give you room to remove the bolts from the intake manifold to the head

Clean the Intake Manifold/plenum ,the Cylinder head, and the oil filter adapter
(I used like 8 cans of carb cleaner)

Also replace the PCV valve, it is 19mm, use wrench or socket. (Note I would cut the hose to the PCV, it easier that
trying to use a pliers to remove the clamps
Now reverse everything and toque everything to specs,

Gaskets you will need:
Intake and Plenum gaskets
Oil Filter Adapter gasket, you find in the dealer, for 3-5 bucks
Copper Spay, helps keep gaskets in place.
