Buying Guide
When selecting an oil catch can, consider fitment, capacity, and design features that affect performance and maintenance.
- Compatibility: Check whether the unit is designed for your PCV system and engine type. Some models target specific GM trucks, while others claim broad vehicle compatibility.
- Capacity: A 300 ml size is common and offers a balance between space and oil collection. Larger bays may be needed for high-blowby engines or race applications.
- Design: Baffled designs trap oil and moisture more effectively, reducing carbon buildup. Removable baffles and steel wool can enhance filtration.
- Hose Kit and Fittings: Durable NBR hoses with secure thread sizes (often M16×1.5) ensure leak-free installation. Include a complete hose layout if possible.
- Breather Filter Options: Some units offer breather filters to vent before PCV or as an inline seal. Decide based on your PCV configuration and ventilation preferences.
- Maintenance: Look for easy accessibility for cleaning and inspection. Some products include dipsticks or clear sightlines for oil level checks.
- Installation Space: Ensure adequate room in the engine bay for can, hoses, and fittings without interfering with belts, pulleys, or other components.
- Durability: Materials such as aluminum offer lightweight strength and corrosion resistance; check hose quality for heat resistance and wear.
Consider a model that provides clear installation instructions, a solid warranty, and compatibility notes for your specific vehicle year and model. For enthusiasts upgrading older platforms or high-performance engines, a baffled can with a robust hose kit typically yields the best long-term intake cleanliness and engine protection.
