The Damond Motorsports Stage 2 Oil Catch Can Kits are an optimal upgrade to an existing Stage 1 OCC kit. The DM Stage 2 OCC kits are intended for customers running a Stage 1 OCC kit, and who are looking to further reduce crankcase pressure, blow by from the valve cover PCV port, or both. With the Stage 2 OCC kits there are a variety of PCV routing options you can choose from, to pick which option will best suit your engine’s PCV needs.
In these diagrams, the routing for the Stage 1 OCC kit is in black and the Stage 2 OCC kit is in green. Routes 2 & 3 require a PCV plate, the Damond Motorsports PCV plate is available here. To further explain the routing options, their pro/cons, and what we recommend them for, please check out our PCV blog
