£474.00 (Inc VAT)

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.

Kit Includes (Photos shown with drain valve not included):

  • Custom-spec oil catch can (available in brushed stainless or wrinkle-black)
  • Custom brushed aluminum mounting bracket
  • Threaded Plug
  • Long rubber hose with OEM connector
  • Short rubber hose with OEM connector
  • 3 nuts, 3 bolts,
  • Zip ties

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 inlet.

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 loose.

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:
