Buying Guide
What is an oil catch tank and why do I need one?
An oil catch tank filters blow-by gases by trapping oil droplets and moisture before they circulate back into the intake. This reduces carbon buildup, helps maintain engine efficiency, and can extend engine life in high-performance or daily-driven vehicles.
Capacity and size: how much should you choose?
Capacity ranges from about 300 ml to 400 ml for most street cars. Racing or turbo applications may benefit from larger canisters to reduce maintenance frequency. Consider space constraints in your engine bay and hose routing when selecting size.
Material and durability: aluminum versus other metals
Aluminum is common due to light weight and corrosion resistance. Billet aluminum variants offer extra durability for long-term use. Check for anodized finishes when choosing color or aesthetic alignment with your build.
Breather filters and venting options
Some cans include breather filters for pre-PCV systems, while others serve as sealed reservoirs. Decide if you need venting options or a sealed setup based on your vehicle’s PCV configuration and emissions requirements.
Installation considerations
Look for compatible hose sizes (usually 3/8″ ID) and standard thread sizes (commonly M16x1.5). Confirm hose routing, clearance around manifolds, and mounting points. A tidy install reduces the risk of hose kinks and ensures consistent performance.
Maintenance and care
Check the can’s bottom for oil buildup and empty as needed. Replace any damaged hoses promptly. Periodic inspection helps ensure the catch can remains effective in preventing blow-by recirculation.
