Idea is to route coolant through these to help the AOS to reach the same temperature as the engine.Drain Port – dumps the oil back into the port on the top of the block.One on the top of the block, under the intake, which is the main drain line where the oil gets redeposited.Two that go to the valve cover breather ports, one on each side of the engine.Side – 3 ports – To relieve crankcase pressure Ports are located on the side, top and bottom of the product. The AOS is sometimes referred to as the “Octopus” because of the multiple hoses, attached to ports, that come off the part. A Catch Can requires ongoing oversight and maintenance as Can itself must be emptied. To keep this simple…think of the Catch Can doing everything that the AOS can do, but with one big difference it catches the oil and does not recirculate it into the engine.
The AOS helps to reduce blowby, creating a cleaner system and delivers oil back into the intake manifold and out of your combustion chamber. This secondary combustion (that should not be there) is the “knock” that can destroy an engine. Engine knock is an audible sound that you can hear and occurs when the combustion of the piston is coupled with a combustion of oil vapors in the cylinder. The PCV from the factory is not as efficient as it should be and can allow oil to make it by the piston rings (blow-by), into the combustion chamber, thereby creating the potential for smoke, loss of power, decreased gas mileage, and even catastrophic engine failure leading to expensive repair bills.Īs oil vapor makes it back into the engine, engine knock can occur. The PCV helps to reduce blow-by at seals and gaskets by removing crankcase gasses generated by the combustion process. The PCV system was developed to reduce emission, crankcase pressure, oil leaks and blow-by. To answer that question, we need to look at the Positive Crankcase Ventilation system (PCV) which it is decades old technology. You might be asking yourself, “Why is oil getting into the tract/combustion chamber in the first place?” The AOS, sometimes called the Octopus, is meant to help during the combustion process by keeping oil vapors out of the intake tract and the engine combustion chamber. What is an Air Oil Separator (AOS) and what does it do? Some features will vary from vehicle to vehicle, but overall terms and features should be applicable between various makes/models. For this article, we will look at the application of an Air Oil Separator from IAG to a 2015+ Subaru WRX featuring the FA20 engine.
