Get the Most from Your Engine with Proper Catch Can Plumbing Techniques

Whether you’re a car enthusiast or just want to keep your engine running smoothly, proper catch can plumbing techniques are essential for ensuring maximum performance and longevity of your vehicle’s engine. Catch cans are designed to capture and separate oil and other contaminants from the crankcase ventilation system, preventing them from re-entering the engine and causing damage. By using the right plumbing techniques, you can ensure that your catch can is functioning at its best and helping to keep your engine in top condition.

Choose the Right Catch Can

The first step in proper catch can plumbing is choosing the right catch can for your vehicle. There are different types of catch cans available, including baffled and non-baffled models, and it’s important to select one that is suitable for your specific engine and driving conditions. Baffled catch cans are generally more effective at capturing and separating oil and contaminants, making them a better choice for high-performance or heavily modified engines.

Positioning and Installation

Once you have selected the appropriate catch can, it’s crucial to position and install it correctly in your vehicle. The catch can should be mounted in a location that allows for easy access and maintenance, and it should be installed in-line with the crankcase ventilation system to effectively capture and separate contaminants. Proper positioning and installation are key to ensuring that the catch can operates efficiently and effectively.

Using Quality Hoses and Fitting

In addition to selecting the right catch can and properly installing it, using high-quality hoses and fittings is essential for proper catch can plumbing. The hoses and fittings connecting the catch can to the crankcase ventilation system should be durable, heat-resistant, and capable of withstanding the pressures and temperatures present in the engine bay. Using inferior hoses and fittings can lead to leaks, blockages, and other issues that can compromise the effectiveness of the catch can.

Regular Maintenance and Inspections

Even with the right catch can and proper plumbing techniques, regular maintenance and inspections are necessary to ensure that the catch can continues to function as intended. Periodically checking the catch can for oil and contaminants, emptying and cleaning the catch can as needed, and inspecting the hoses and fittings for signs of wear or damage are all important steps in maintaining the effectiveness of the catch can.


Proper catch can plumbing is essential for getting the most from your engine and ensuring its long-term performance and reliability. By choosing the right catch can, positioning and installing it correctly, using quality hoses and fittings, and performing regular maintenance and inspections, you can maximize the effectiveness of your catch can and help keep your engine running smoothly for years to come.
