The Subaru BRZ is a popular choice among car enthusiasts, especially for those looking to enhance performance through modifications. One such modification that can significantly improve turbo performance is the installation of a catch can. A catch can helps eliminate oil blow-by, which can lead to a cleaner intake system and better engine efficiency. In this article, we will explore the steps for installing a catch can on your Subaru BRZ.
Understanding Oil Blow-by
Oil blow-by occurs when oil vapor escapes from the engine’s crankcase into the intake system. This can lead to several issues, including:
- Increased carbon buildup in the intake manifold.
- Reduced engine performance and efficiency.
- Potential for increased oil consumption.
Benefits of Installing a Catch Can
Installing a catch can can provide several benefits for your Subaru BRZ, such as:
- Reduction of oil vapor entering the intake system.
- Improved engine performance and responsiveness.
- Longer engine life due to cleaner internals.
Choosing the Right Catch Can
When selecting a catch can for your Subaru BRZ, consider the following factors:
- Capacity: Choose a can that can hold enough oil vapor without frequent emptying.
- Material: Look for durable materials like aluminum or high-quality plastic.
- Design: Opt for a design that fits well in your engine bay and has easy access for maintenance.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Catch can kit.
- Socket set.
- Screwdrivers.
- Hoses and clamps (if not included in the kit).
- Drill (if necessary for mounting).
Step-by-Step Installation Guide
Step 1: Locate the PCV System
The first step in installing a catch can is to locate the Positive Crankcase Ventilation (PCV) system in your Subaru BRZ. This is typically found near the engine block and is connected to the intake manifold.
Step 2: Remove the PCV Hose
Carefully disconnect the PCV hose from the intake manifold. You may need to use a screwdriver to loosen any clamps holding the hose in place.
Step 3: Prepare the Catch Can
Attach the necessary fittings to your catch can according to the manufacturer’s instructions. Ensure that everything is secure and ready for installation.
Step 4: Mount the Catch Can
Find a suitable location in the engine bay to mount the catch can. This should be accessible for emptying and maintenance. Use the provided brackets or drill holes if necessary to secure the catch can in place.
Step 5: Connect the Hoses
Connect the hoses from the PCV system to the catch can. Make sure to follow the correct flow direction as indicated by the manufacturer. Use clamps to secure the hoses to prevent leaks.
Step 6: Reconnect the PCV Hose
Reconnect the PCV hose from the catch can to the intake manifold. Ensure that all connections are tight and secure.
Step 7: Check for Leaks
Start your engine and check for any leaks around the catch can and hose connections. If everything is secure, you are ready to go!
Maintenance Tips
To ensure your catch can functions effectively, follow these maintenance tips:
- Check the catch can regularly for oil buildup.
- Empty the can as needed, typically every few hundred miles or as recommended by the manufacturer.
- Inspect hoses and connections for wear and tear.
Conclusion
Installing a catch can on your Subaru BRZ is a valuable modification that can enhance turbo performance by reducing oil blow-by. By following the steps outlined in this guide, you can successfully install a catch can and enjoy the benefits of a cleaner engine and improved performance.
