*Please note, since the V2 AOS Kit removes the PCV valve from the smog system, it is for off-road use only in CA. The V2 features an added coolant bypass line to keep the canister at operating temps at all times, solving the condensation issue. We recalled the V1 and replaced it with the V2. Water and oil do not mix, so this environment was not allowing the canister to perform it's job of separating the two. Cold air from the hood scoop would hit the canister right on, creating the condensation and water to form on the inside. When the product was launched worldwide, colder and frozen climates experienced condensation. Due to our warmer climate here in Southern California, our testing did not cover frozen climates. Adapting concepts from other manufacturers solutions, we engineered our own swirl pot solution to keeping oil out of the intake. We were suffering consistent engine failures due to oil starvation and excessive detonation. In 2005, the V1 was our original design on our race vehicles. What are the differences between versions? Each canister is put through a pressure test post-manufacturing. The Crawford AOS is the only design that forces oil through a labyrinth system, with each change of direction increasing the separation efficiency.Takes half the time to install compared to other AOS kits.We offer the only Dual Chamber system in the industry, without the need to delete any smog components for installation.Our V3 has the latest technology not seen anywhere else patent pending. What makes a Crawford AOS stand above the rest?
#Why install oil catch can full
This allows your Subaru's engine to purr efficiently at its full potential, without having to worry about your avoidable detonation. Having a secondary system is your fail-safe for detonation that is un-related to a poor tune. Not only will you consume less oil, the lack of excess helps to maintain the ultimate mixture in your cylinders which in turn maximizes your power output. Any added stress/heat from power components and higher G-Forces increases the amount of excess oil that ends up in your intake. This failure is amplified when modifying power components. Over time, this excess oil begins to build up making the detonation more frequent and damaging. Detonation is what causes the infamous ‘ringland failure’: a term that all of us Subaru owners have become unnecessarily accustomed to. Another word for this is detonation - an engine killer. Since oil is naturally combustible, this causes irregularities with the controlled explosion that happens in this environment, subsequently creating multiple explosions. G-Forces push excess oil to the tops of the pistons. Subarus engines are notorious for higher than average oil consumption. They are horizontally opposed, meaning that their pistons move side to side.
