Damond Motorsports Focus ST Stage 2 Install Guide

For those looking to collect blow-by contaminates from the upper side of the PCV system, this is the kit for you. We recommend this kit AFTER a Stage 1 kit, or along with it, especially if the car sees higher amounts of boost, or boost for prolonged periods of time as in racing applications.

Tools required/purpose:
Socket wrench:
7mm socket/loosen clamp on intake piping
8mm socket/loosen clamp on intake piping and attach bracket to camshaft housing
10mm socket/attach bracket to OCC
Flathead screw driver/tighten hose clamps
Torque wrench
Hose cutter, or razor blade/trim hoses 

Step 1:
Unbox your Damond Motorsports OCC kit.

Provided in your kit are these components:
1: Damond Motorsports Oil Catch Can(VTA optional)
2: lengths of 3/8” hose
1: small length of 1⁄2” hose, with 1⁄2” to 3/8” reducer barb
1: small length of 5/8” hose, with 5/8” to 3/8” reducer barb
1: small length of 3⁄4” hose, with 3⁄4” to 3/8” reducer barb
1: long length of drain hose
1: 1⁄2” to 3/8” reducer barb
1: straight quick connector
1: 90 quick connector
1: OCC mounting bracket
1: bracket bolt
1: drain valve 90 barb
6: hose clamps, ranging in sizes
5: zip ties

Step 2:

Begin with removing the engine cover by pulling straight upward.

From above the engine, loosen the hose clamps securing the intake tube in place above
the engine, along with the bolt securing the intake tube to the camshaft cover. Remove
the tube. If you have an aftermarket intake, refer to the manufacture’s instructions for
install and removal of the upper piping.

Step 3:

Locate the upper PCV tube connected to the lower intake tube and valve cover. Remove
the tube from the valve cover, by squeezing in the connectors and pulling the tube away. 2015 and newer cars the hose is shown here, pre-2015 ST's do not have the sensor on the hose. 

Step 4:

If the hoses are not assembled with the connectors, insert the small straight and 90 connectors into the proved hose as shown. We recommend using a little bit of lube and warming up the hoses in hot water, or with a heat gun, to make them more pliable and able to install the connectors.



Step 5:

Route the hose with the 90 connector to the valve cover. Once routed push the connector onto the valve cover until it clicks into place, it will be pointing slightly downward. (this hose will go to the bottom OCC port)


Step 6:

Route the tube with the straight connector to the factory hose, and connect the connectors. If you have an aftermarket intake, use one of the various supplied connectors and connect the new hose to your intake. Route the hose over to where the OCC will sit. (this hose will go to the top OCC port)


Step 7: 

Unbolt the 8mm fuel line retaining bolt shown here.

Step 8:

Test mount the OCC in place. Attach the bracket to the OCC as shown with the provided 10mm bolt. Align the hoses with their respective ports(top port intake hose, bottom port valve cover hose). Mark the hoses to where they'll need to be trimmed. Be sure to include some slack in the hoses. Remove the OCC and cut the hoses where marked. 


Step 9: 

With the hoses now cut to length, attach them to the OCC, and secure them with the provided hose clamps. Once the hoses are attached, route the OCC down to where it would be located, place the OCC bracket over the fuel line retainer, as shown. Using the 8mm bolt removed earlier, secure the OCC. TQ spec: 15Nm or 120-140in/lbs


Step 10:

Re-install the upper intake tube. Start the car and check the system for any leaks. 

Step Optional:
Each DM OCC kit contains a drain barb and drain hose. You may install these
components, if you wish to drain the OCC without removing it.
-Install the barb into the OCC drain valve.
-Install the drain tube to the drain barb.
-Secure the drain hose to the engine with the provided zip ties, keep it from hitting
moving components such as the shift cables.
-Place the undertray back on, and secure it with a few bolts.
-Reach down to the drain tube, and mark with a paint pen to determine where the hole
will need to be drilled. You may also pull down on the cover slightly under where the
drain hose is located to mark a drain hole.
-Drill a large enough hole in the undertray to route the drain hose through (bigger than
1⁄2” should do)
-Re-install the undertray, and cut off the excess hose, so that about only 1⁄2-1” is
protruding from the undertray.

Draining the OCC:
The DM OCC features an easy to use drain valve. When the valve arm is vertical the
drain is open, and when the arm is horizontal the valve is closed. Be sure to not run the
engine with the valve in the open position, as this will cause poor idling conditions and
stuttering. Drain the OCC contents into a container as you would engine oil, and dispose
of it properly and legally. Be sure to wear protective gloves when handling the OCC
fluids, as well as any engine oil, for that matter.

We hope you enjoy our Focus ST Stage 2 OCC kit!
