N18 Competition Catch Can -Page1

Tools Needed
7/16” wrench
5/16” Allen Key
Flathead Screwdrivers
Scissors/Blade (to cut hose

Note to user: R60 Cooper S will have to
make their own modifications to find a
location to mount the Catch Can. 2011
JCW use the R56 or N14 Competition
Catch Can.

1) Check the picture and make sure you
have all the parts and tools listed

2) Disconnect the PCV hose.
On the intake pipe side, slide back the metal
clip and pull off the hose from the sensor. Then
on the valve cover side, Squeeze on both sides
of the clip and pull back. As you are squeezing,
you may need to rock the clip off of the
retention point



3) Assemble the Fittings
Install o-rings onto the Valve Cover fitting. Screw on the 120
deg AN Fitting to the Valve Cover Fitting. Screw on the 90 deg
AN fitting to the Intake Pipe Fitting. Install the fittings and reinstall
the sensor plug that was detached from the factory PCV hose.

4) Assemble the Catch Can
Install the drain plug; put the washers onto the buttonhead
screws and use them to secure the bracket onto the catch can.

5) Mount Catch Can
Mount the Catch Can using the bolt and lock washer supplied,
either on the factory tab next to the Intake box. If you have the
factory alarm on that tab, you may choose to mount the can
under it or call your aftermarket dealer for an additional bracket
to mount the can to the firewall. You may also choose to mount
the catch can next to the washer fluid tank if you have an interferring
aftermarket intake. Please note that the catch can will touch
the tab on the factory intake as well as touch the ECM housing. If
you choose to mount the catch can in a different locaton, we recommend
that location be away from heat as the cooler the catch
can is, the more condensation and oil it will catch.

6) Cut hoses to length and install
When looking at the ports, (bracket is away from
you) The left side port is input (from valve cover)
and the right side port is output (to intake pipe).
We suggest securing the hoses so that it has
clearance from the hood. If your hoses touch the
hood, check them regularly for wear and replace
if needed.


7) Maintenance
Check the Catch Can regularly (at minimum, every oil service
interval) . Drain contents of the can using the drain plug when
