Damond Motorsports Focus ST Stage 1 Location 1 Oil Catch Can Kit Install Guide

Damond Motorsports Oil Catch Can kits come with everything needed for an optimized Oil Catch Can system. An oil catch can is, in a sense, a filter for the positive crankcase ventilation system. Here is our install guide for the Stage 1 Location 1 kit. 


Tools required/purpose:


Jack and jackstands or lift or ramps/to lift the car

Socket wrench:

Long 6” extension/remove intake manifold bolts

7mm socket/loosen clamp on intercooler piping

10mm socket/attach bracket to OCC, remove intake manifold, disconnect battery

Flathead screw driver/tighten hose clamps

#30 Torx driver or socket/remove under tray

Torque wrench


Step 1:

Unbox your Damond Motorsports OCC kit. You’ll want to prep the OCC kit to be installed. Attach the hoses as shown, with the check valve hose going to the top port on the OCC, and the hose with the straight connector going to the bottom OCC port, and secure the hoses with the provided hose clamps.

Step 2:

Begin with removing the engine cover by pulling straight upward. Next the battery cover and disconnect both the negative and positive battery leads from the terminals, and secure the wires from contacting the battery terminals. Note: Not disconnecting the battery may cause electric shock, as you’ll be working around the vehicle’s starter motor. Record all radio and other presets, as they may need to be programmed in later.

Step 3:

From above the engine, loosen the hose clamp securing the intercooler tube to the throttle body.

Step 4:

Safely lift the car in the air, using a lift or jack, and support the car on jackstands. Refer to the owner’s manual for proper jack points.


Step 5:

Remove the engine undertray. Begin with the 3 front air dam screws(green), then the remaining 8 undertray screws(red):

Step 6:

Pull the intercooler tubing from the throttle body. If you have the factory tube installed, you can bend it out of the way (Place a clean towel partially in the tube to prevent debris from entering). If you have an aftermarket intercooler piping, refer to the manufacture’s instructions for removing/installing the tube leading to the throttle body

Step 7:

Disconnect the throttle body connector. Begin by sliding the red clip on the throttle body connector outward, and depressing the clip in the area shown in yellow, and slide the connector from the throttle body. Pull the wire gently downward to unsecure it from the wire clip on the throttle body itself (shown in blue)

Step 8:

Un-clip the EVAP line from the intake manifold(blue arrows), and remove the 5 10mm bolts securing the intake manifold to the head.

Step 9:

Pull the manifold slightly away from the engine, to better access this connector. Slide the connector from its retainer on the manifold(red arrow)

Step 10:

With the manifold un-bolted, put it away from the head as shown. This will give you enough access to install the OCC lines.

Step 11:

Disconnect the PCV hose from the intake manifold. Squeeze the connector on both sides, and pull back away from the manifold to disconnect it.

Step 12:

Rotate the PCV valve, hose, and connector within the hose, into the orientation shown here, where the connector port is facing where the OCC will be mounted.

Step 13:

It is time to connect them into the corresponding PCV connections. Begin with the straight connector; this will go into the PCV hose connector that was re-aimed earlier. When inserting the hose into the connector, you’ll hear a satisfying “click” ensuring that the connectors have mated properly.


Now with the 90 degree connector, coming from the check valve hose, insert the connector into the intake manifold port. You’ll once again hear a satisfying “click” ensuring that the connectors have mated properly.

Shown from underneath:

Shown here is a photo of how this hose is routed: 

Carefully inspect all connections, to double check that the connectors are fully seated.

Step 14:


Slide the connector, removed earlier, back onto the retainer on the manifold


Carefully inspect the gaskets on the intake manifold and mating surfaces. Clean any debris on the mating surfaces with a wet rag. Mount the manifold to the head, ensuring all manifold gaskets are fully seated in place in the manifold. Bolt the manifold to the head, and tighten the bolts to 150-175in/lbs or 12-15ft/lbs.


Connect the throttle body wiring connector back into place, by sliding the connector fully on, and pressing the red clip. Re-secure the wiring to the wire clip on the throttle body itself.


Install the intercooler tubing to the throttle body(remove any a towels or rags placed in the tube prior). If you have an aftermarket intercooler piping, refer to the manufacture’s instructions for removing/installing the tube leading to the throttle body.


Take the OCC bracket and loosely mount it to the OCC and intake manifold threaded tab. With the OCC in place, tighten the bolts provided to 90-120in/lbs or 7.5-10ft/lbs.

Step 15:

Reinstall the remaining components as were removed, and reconnect the battery. Now check the system for any leaks, and start the car. Let it run for a little as you double check all the connections for 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 from above the engine.


-Install the barb into the OCC drain valve.

-Place the undertray back on, and secure it with a few bolts.

-Reach down to the OCC, 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 with the OCC is located to mark a drain hole.

-Drill a large enough hole in the undertray to route the drain hose through (bigger than ½” should do)

-Install the drain tube to the drain barb

-Secure the drain hose to the engine with the provided zip ties

-Re-install the undertray, and cut off the excess hose, so that about only ½-1” 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 1 OCC kit!


For the relocation kits:


-Follow steps 2-12 in this guide

-Unbolt the OCC from the ECU bracket and remove the OCC from the vehicle with hoses installed still attached to the OCC

-Remove the OCC hoses from the OCC

-Cut the OCC hoses to the measurements shown, be sure the hoses are straight when you measure and cut

-Cut the hose with the check valve to 11” from where the 90 OEM fitting is

-Cut the hose with the straight OEM connector to 9” from where the 90 OEM fitting is

-Attach the hoses to the OCC as shown in step 1

-Continue steps 13-15
