Oil Catch Cans/Air Oil Separators (AOS)
Oil catch cans and air/oil separators for performance vehicles
The oil system in your performance vehicle is essential for the proper lubrication of all engine components, which means better performance and protection of all parts under the hood.
Whether you have a wet sump or dry sump system makes no difference. It does not matter where the oil comes from – your vehicle will need a constant supply to keep everything lubricated and moving as it should. This is especially important for performance vehicle and car enthusiasts, so you can rely on this supply at all RPMs and under all conditions when you are pushing your car to its limits.
We stock all the aftermarket components required to ensure you have this flow and proper lubrication in extreme conditions. These include oil catch cans and air/oil separators that will give you total reliability.
Oil catch cans to protect your engine and manifold.
Over time, vapours can lead to build-ups of oil and contaminants in your engine bay, especially inside your manifold. These build-ups can be caused by blow-by gases that from the crankcase and also when oil begins to get past the intake valve seals, leading to reduced performance and higher risk of engine damage.
Oil tanks are simple devices that can help prevent this build-up. They plug into the hose that runs from the top of your crankcase to the intake manifold and capture the excess oil and vapours that can travel through this hose. They effectively act as a filter. As long as these tanks are emptied regularly, you will prevent build-ups and damage to your intake manifold.
Air/oil separators can also help prevent build-up
To escape the hassle of having to drain a can or tank, you can also consider air/oil separators that provide the same protection level, only with a drainage device to ensure there is never any overflow. This allows the oil that has been blocked from entering the manifold to drip back into the oil pan, so you have ongoing protection without any manual maintenance.
