Aston Martin V8 Vantage Air/Oil Separator Catch-Can


Keep your intake manifold clean as a whistle and free from PCV blow-by with this AOS Catch Can
kit. Designed by Aston owner & enthusiast Richard Seidlitz to
collect blow-by and prevent clogging of your PCV system. Perfect and
easy bolt-on installation, looks totally OEM, as thought it left the
factory with the catch can installed.

Catch can is all steel & aluminum and internally baffled for maximum performance.

Installation Instructions:

Tools Needed
8mm socket
10mm socket
Allen keys

Step 1
Attach the hoses to the catch can. The long one goes on the top hose
nipple, and the short one goes on the bottom hose nipple. (The allen
head screw at the bottom of the can is the drain port. Do not turn over
the can to drain.) Use the zipties to prevent oil from getting out
from between the hoses and can. I included extra zipties so you can use
them where the connectors fit into the hoses as well.

Step 2
Remove the hard plastic tube going from the PCV to the intake manifold.
You’ll notice that one side of the quick-release on the tube at the PCV
side is pointed down. I’ve found that a long, flat-head screwdriver
can be used to push in that side while using your finger to push in the
top side.

Bag and tag the plastic tube for later use in case you decide to remove
the kit. Clean any oil you find in the PCV outlet or intake manifold

Step 3
Remove the bolt holding the power steering fluid reservoir in place. It
will spring open so be very careful not to lose the bolt when it comes

Step 4
Move the power steering fluid reservoir to the side so you can access
the next two bolts. DO NOT disconnect the hoses from it! Use the 8mm
socket to remove those two bolts.

Step 5
Install the catch can mounting bracket and re-install the two bolts you
just removed. The bracket will go between the bolt heads and the rubber
isolators. DO NOT over-tighten the bolts! Inside the rubber isolators
there are metal cylinders that can crush if the bolts are
over-tightened. Once the two bolts are back in and the catch can
mounting bracket installed, return the power steer fluid reservoir to
its place and reinstall the bolt to keep it in place.

Step 6
Install the catch can! I’ve found that the easiest way to install the
catch can is to put on the hoses first (as in Step 1), then position the
can in place with the hoses pointing toward the back of the car, then
rotate it to align the hoses with the PCV and intake manifold.

There are three hard plastic hoses that run parallel to each other. The
long hose coming from the top of the catch can will go above these and
connect to the intake manifold. The short hose coming from the catch can
will go below the three hard plastic hoses and connect to the PCV. Once
the hoses are connected, the catch can will rest in place.

Step 7
Use the 10mm socket and allen key (5mm, I think) to install the three
bolts (or just two, if you prefer) to attach the catch can to its
mounting bracket. It should now look like this:
