Step 1: Remove factory accordion hose that leads from the Intake manifold to the Front
PCV assembly. This is done by pinching the connectors on both sides and pulling away.

Step 2: Install the manifold block off plug. Make sure the O-ring is properly seated in its
groove before installing. Apply a dab of motor oil to the O-ring to help it slide on. It is easiest to install by doing a slight twisting motion. When you have it on the manifold,
look at the opening on the plug and make sure the bolt holes have cleared the lip on the
manifold. When this is done, apply a small drop of blue loctite to each one of the set
screws. When installing the set screws DO NOT TIGHTEN THEM. These screws hold
the cap in place by locking it against the lip on the manifold. There is no need to apply
force to them. Allow the loctite to dry before driving.

Step 3: Remove the front PCV assembly. Start by removing the hose on the driver side.
The clip that holds it in place has 4 teeth. Remove the side teeth and the top tooth by
gently lifting them up and over the lip on the nipple one at a time with your flat head
screwdriver. When those are free of the lip, slide it off. Be patient with it, don’t break the
clip. When the hose is removed, then remove the 4 T25 torx screws holding the front
PCV in place. Make sure to keep the screws as they will be re-used. With the screws
removed the front assembly will come off.

Step 4: Install the PCV Nipple and the PCV Guidance Block. You must do this as
follows for the part to fit properly. First install the guidance plate with the nipple off of
it in order to access all the screw holes. Line it up and re-install using the factory screws.

Once installed and sitting flush install the PCV hose and snug it tight with an adjustable
wrench. Now install the factory PCV hose onto the nipple. This is a tight fit and you will
want to guide the O-rings into the hole with the tip of your flat head screwdriver.
Note: Do not apply to much force to when re-installing the factory hardware. The needed
torque is 30 in/lbs so take it very easy on them.

Step 5: Install the 90 degree fitting on the top of the catch can. Apply a bit of blue loctite
before installing. Wrap the supplied adell clamp around the can just below the side fitting
and attach it to the supplied bracket using the allen screw and lock nut. Once secured to
the bracket it is time to install.

Step 6: Remove the two T30 Torx screws on the passenger side of the radiator shroud
and then slide the bracket between the shroud and the metal backing plate. Put a little bit
of pressure with your hands on the shroud when re-installing the screws to make sure
everything lines up properly. Snug the screws down.

Step 7: Now run your lines. The fitting on the right side of the plate will be connected to
the side port of the catch can. The fitting on the left side will go to the top fitting on the
can. Leave just a little bit of slack to allow for engine movement. Once cut to length,
secure the lines with the supplied hose clamps. The side fitting does not require a hose
clamp.

Step 8: Start the car up and check for leaks. If the engine bucks or surges then you have a
leak and will need to make sure everything is seated properly. If you notice a putting
sound coming from your intake it is caused by the check valve in the PCV port on the
rear of the valve cover. This check valve is sealed at rest and when pressure builds up
behind it the valve will open creating a putt sound. This is not harmful and if found to be
an annoyance the check valve can be removed from the rear port.
Maintenance: For the first few weeks you have the can installed monitor how much
blowby you are collecting. You will need to monitor how much blowby from your
individual car ends up in the catch can and judge how often you need to drain. This will
vary from car to car.
You will collect a mixture of oil, water, and fuel vapor in your catch can. Expect the
quantity of water to greatly increase during the winter months. Every 3-4 months remove
the top fitting and clean out the can with brake cleaner. Also clean out your catch can
lines.
It is of utmost importance that you do not let the catch can reach full. If the can is allowed
to become full the crank case pressure will no longer be able to be vented which can lead
to engine problems.

**Important Note**
Customers in regions of the world that drop well into the freezing temperatures during the
winter will need to keep a watchful eye on the volume of water collected in the can. One
of the main fluids caught in the can is condensation (water). In the winter months the
amount of condensation caught in the can will dramatically increase. If left in the can in
freezing temperatures there is a possibility that this water could freeze. If frozen, pcv
flow will be inhibited. Make sure to keep an eye on your fluid levels.
