Installing an oil catch can is a great way to prevent carbon build-up in direct injection engines. Here are some key things to know before you begin:
1. Purpose of an Oil Catch Can
An oil catch can intercepts blow-by gases from the crankcase before they reach the intake manifold. These gases contain oil vapors and contaminants that can lead to carbon deposits on intake valves. By trapping these substances, the catch can helps maintain engine efficiency and longevity.
2. Choosing the Right Catch Can
- Look for a baffled or filtered catch can to ensure effective oil separation.
- Ensure it has a drain valve for easy maintenance.
- Select a model that fits your engine bay and PCV system configuration.
3. Installation Process
- Locate the PCV System: Identify the hose that connects the valve cover to the intake manifold.
- Mount the Catch Can: Secure it in a convenient location using brackets.
- Connect the Hoses: Route one hose from the PCV valve to the catch can’s inlet and another from the catch can’s outlet to the intake manifold.
- Secure Everything: Use hose clamps to prevent leaks and ensure proper airflow.
4. Maintenance Requirements
- Periodically empty the catch can to remove collected oil and contaminants.
- Inspect hoses and connections for leaks or blockages.
- Clean the catch can to maintain optimal performance.
5. Potential Drawbacks
- Some catch cans require frequent draining, depending on driving conditions.
- Improper installation can lead to vacuum leaks, affecting engine performance.
- Certain models may not be legal in all regions, so check local regulations.
