Oil Catch Tank Installation Diagram and Setup Guide

For optimal performance, ensure the proper placement of the separator unit in the vehicle’s ventilation system. The device should be mounted securely to avoid leaks or disconnections, particularly in high-stress conditions. Position it near the intake manifold or wherever the system allows the most efficient capture of harmful vapors and excess moisture.
Start with a suitable location. Choose a space that provides enough clearance for hose connections, without obstructing airflow or access to other engine components. This will improve both accessibility during maintenance and the overall efficiency of the system.
Next, connect the hoses to the separator’s input and output ports. It’s important to use high-quality, durable tubing that can withstand engine temperatures and pressure changes. Check that the connections are tight and free of any leaks to maintain a consistent flow and prevent system failures.
Ensure proper sealing of all components to prevent any bypass of gases that would compromise the function of the separator. Regularly inspect the unit to ensure no buildup or contamination, which could interfere with its efficiency. Always follow the manufacturer’s specific guidelines for the ideal setup and maintenance schedule.
Setup Guide for the Separation System

Position the separator unit near the engine bay, ensuring it is accessible for regular checks and maintenance. Attach the main intake hose to the engine’s crankcase vent port, ensuring a secure and tight connection to avoid any leaks. The other end of the intake hose should lead to the designated inlet of the separator unit.
Next, connect the outlet port of the separator to the intake manifold or designated vacuum source, following the manufacturer’s specifications. Use sturdy, heat-resistant hose clamps to ensure the hoses are firmly secured at both ends, preventing disconnections during operation.
Make sure the unit is installed at a slightly inclined angle to promote the natural flow of condensed substances into the reservoir, ensuring smooth drainage. Check for any potential points of contact with hot engine components to prevent damage to hoses and other parts.
After confirming all connections, run the engine and inspect for any visible leaks or irregularities in the airflow. Tighten all clamps as needed and double-check that no hoses are kinked or obstructed, as this could affect the overall function of the system.
It is recommended to check the system periodically to ensure it remains free from blockages, and to empty the container once it reaches capacity to avoid overflows or system malfunctions.
Choosing the Right Location for the Canister Setup

Place the canister in a location that minimizes the length of the hoses, ensuring efficient fluid flow. This reduces the chance of air pockets and fluid starvation. Here’s where you should focus:
- Proximity to the Crankcase Ventilation System: Position the container as close as possible to the breather system to minimize hose lengths and maximize performance.
- Accessible for Maintenance: Ensure the unit is in a spot that allows for easy checking, draining, and cleaning. Avoid locations that are hard to reach or hidden behind components.
- Under the Hood: Install in a location that allows for sufficient airflow to prevent heat buildup. The container should not be near excessive heat sources like exhaust manifolds.
- Stable and Secure Mounting: Make sure the chosen spot provides stable mounting to prevent vibrations from loosening the connections. Use robust brackets or custom mounts.
- Avoid Obstructions: Ensure the unit is not obstructed by other components, such as the radiator or battery, to maintain proper airflow and accessibility.
- Position for Drainage: Place the unit in a position where the fluids can easily drain into a collection area without creating a mess or requiring excessive tilting.
By considering these factors, you can improve the system’s efficiency and make sure maintenance is straightforward.
Step-by-Step Guide to Plumbing the Engine Ventilation System
1. Begin by selecting a suitable location for the reservoir. Ensure it is easily accessible for regular maintenance and close to the engine’s vent pipe for efficient routing.
2. Use high-quality, heat-resistant hoses to connect the engine’s crankcase breather outlet to the reservoir’s input port. Ensure the hose is securely clamped on both ends to prevent leaks.
3. Install a drain hose from the bottom of the container to allow for quick disposal of collected fluids. The drain should direct the fluid into a container or designated area to avoid spills.
4. Attach a return hose from the upper section of the collection unit to the intake system. This ensures any captured vapors are directed back into the engine for reprocessing, reducing emissions.
5. Secure all hoses and fittings with the appropriate clamps to avoid disconnections or leaks during high RPMs. Check for any slack that might cause vibrations or rubbing against other engine components.
6. For optimal function, ensure that the system is slightly inclined so that liquids flow towards the drain and not towards the breather lines. This reduces the chances of clogging or overflow.
7. Perform a final check for leaks by running the engine at idle. Observe all connections, paying close attention to the hose joints. Tighten or replace any components that show signs of leakage.
8. Regularly monitor the reservoir for fluid build-up, and clean or replace the system components as needed to ensure long-term performance.
Common Mistakes to Avoid During Setup
Ensure proper placement of the container–avoid mounting it too low or near hot engine components, as this can cause overheating or poor drainage. The setup should allow for easy access and maintenance, avoiding tight spaces that hinder future servicing.
Incorrect hose routing is a frequent issue. Keep the path as short and direct as possible, ensuring there are no sharp bends that could impede airflow or lead to fluid backup. This can affect performance and longevity of the system.
Don’t neglect proper sealing at connection points. Leaks can develop if hoses or fittings are not tightly secured. Use high-quality, resistant materials that can handle the pressure and temperature fluctuations commonly found in engine compartments.
Never overlook the importance of venting. Ensure the vent is installed correctly to avoid vacuum buildup, which can disrupt engine pressure. Failing to provide adequate ventilation can lead to operational issues and inefficiency.
Always verify that the system is not overly complex or convoluted. Excessive components and connectors can introduce points of failure, making troubleshooting more difficult and increasing maintenance requirements.
After the setup, test for leaks and ensure the system functions under pressure. A thorough check can help identify any overlooked issues before they cause long-term damage.
