The Chase Bays Oil Catch Can is the culmination of hundreds of hours of testing on dozens of builds, street and track. Thisis one of the most important modifications you can do to your engine! It is essential for preventing harmful oil and carbon buildup in the intake system, maintaining octane levels, increasing performance with cleaner inlet air, and properly venting the crankcase pressures in the most aesthetically pleasing, modular, and easiest to install solution on the market.

We started our initial design using CFD (Computational Fluid Dynamics) analysis to simulate input flow under operating conditions ranging from extreme vacuum to extreme boost, optimizing our design to maximize separation of contaminants and maintain flow through. Physical prototypes were then tested over thousands of miles in competitive road race and drift builds as well as on the street to validate our design in the real world, how our customers will use them.

Our catch can is machined from 6061 aluminum, bead blasted, then Hard UV-Proof Anodized Signature Chase Bays Black. The top and bottom are threaded together and sealed with an O-Ring for a leak proof connection that is safe for the most extreme pressurized applications. All hardware is stainless steel. The 10AN ORB inlet and outlet are both on the top for a seamless look and easy routing. Seven different bracket types are offered to make mounting easy.

Air Oil Separation
The inlet is equipped with a stainless steel mesh filter for the best possible air, oil, and water condensation separation before it even enters the tank. Once the oil has passed through the filter, we have created the highest level of Oil Separation Baffling from the Outlet back to engine while maintaining complete flow. There is no return restriction.

Oil Level and Drain
An integrated mini Chase Bays Reservoir Cap Style Dip Stick with a notch shows when the oil is ready to be drained. The Dip Stick is knurled for easier gripping. When the oil is ready to be drained, there is a -4AN ORB port on the bottom of the Can or the lower housing can be removed or we highly highly recommend ourOil Catch Can Drain Kit with petcock.

Fittings
Inlet and Outlet Fittings are offered in -10AN and 5/8 Push-On Hose Barb. Each of those are offered in Straight, 90, and 90 L Fitting styles. The L fitting is great for joining two valve cover outlets into one easily. Two outlets on an Inline-Four Valve Cover (Honda, SR20), Intake and Exhaust Side Valve Covers on Inline-Six (JZ/RB), Two Valve Covers on a V6/V8…this L Fitting will eliminate the need for Dual Catch Can setups for most setups under 450-500hp or special PCV designs, by turning a single catch can into a three- or four-port design.
