Preparation

Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials to streamline the process.

Step 1: Locate the PCV System

Open the hood and locate the Positive Crankcase Ventilation (PCV) system. This is typically found on the engine cover. Familiarize yourself with the layout to identify the connections for the catch can.

Step 2: Remove the Engine Cover

Using a ratchet and socket, carefully remove the bolts securing the engine cover. Set the cover aside in a safe location.

Step 3: Disconnect the PCV Hose

Gently disconnect the PCV hose from the intake manifold. Be cautious not to damage the hose or fittings during this process.

Step 4: Install the AEM Catch Can

Choose a suitable location for the catch can, typically near the intake manifold. Use the provided mounting hardware to secure the catch can in place. Ensure it is stable and will not move during operation.

Step 5: Connect the Hoses

Using the provided hoses, connect one end to the PCV port on the catch can and the other end to the intake manifold. Ensure the connections are tight to prevent any leaks.

Step 6: Secure the Catch Can

Once the hoses are connected, use zip ties or additional mounting hardware to secure the catch can and prevent movement. Double-check all connections for tightness.

Step 7: Reinstall the Engine Cover

Carefully place the engine cover back onto the engine bay. Secure it with the bolts you removed earlier. Ensure everything is aligned properly.

Step 8: Final Checks

Before starting the engine, double-check all connections and ensure there are no loose parts. Make sure the catch can is securely mounted and all hoses are properly connected.

Step 9: Start the Engine

Start the engine and let it idle for a few minutes. Check for any leaks around the catch can and hoses. If everything looks good, take your Civic Si for a test drive.
