Choosing the Right Scion tC Oil Catch Can: Key Factors to Consider
Fitment and Mounting
Correct fitment matters because the engine bay on the Scion tC has limited space and specific PCV hose routing. A catch can that offers vehicle-friendly mounting brackets and multiple orientation options reduces the chance of interference with other components. Consider whether the kit includes dedicated brackets or universal hardware that still allows secure installation.
Mounting location also affects hose length and routing. Short, direct hose runs minimize bends where oil can pool, while flexible mounting options help you avoid heat sources or moving parts. Verify that the chosen location gives easy access for periodic draining and inspection.
Materials and Construction
Durable materials resist corrosion and hold up to repeated thermal cycles under the hood. Look for metal housings with quality finishes or robust plastics rated for automotive use. Threaded drain fittings, anodized surfaces, and reinforced hose connections contribute to longevity.
Solid construction also reduces the chance of leaks or failure under vibration. Well-machined fittings and secure fasteners make routine maintenance simpler and reduce the need for re-torquing after road use.
Internal Separation Design
The way a catch can separates oil from vapors determines how much oil the intake sees over time. Effective designs use baffling, filter media, or coalescing chambers to condense and capture oil droplets while allowing vapors to pass back into the intake. Consider whether the design is serviceable so internal elements can be cleaned or replaced.
A more efficient internal layout typically means longer intervals between drains and less oil reaching intake components, which helps preserve throttle bodies, intercoolers, and intake valves.
Hose and Fitting Compatibility
Compatibility with existing PCV and vacuum hoses simplifies installation and avoids the need for adapters. Check hose barb sizes, included fittings, and whether the kit supplies stainless clamps or reusable fittings. Proper sealing at hose connections prevents vacuum leaks and maintains correct crankcase ventilation behavior.
Also consider the routing: kink-resistant hoses and smooth fittings reduce flow restriction and avoid premature hose wear. Kits that include pre-formed hoses or clear labeling for inlet and outlet reduce installation errors.
Serviceability and Drain Options
Frequent or messy draining can deter regular maintenance, so look for catch cans with accessible drain valves or threaded plugs that allow quick, clean emptying. Transparent sight tubes or level indicators help you know when to drain without dismantling the unit. Easy removal and reinstallation of internal elements make cleaning simpler.
Serviceability also includes how easy it is to access the can in the chosen mounting spot. A design that accommodates common driveway tools and avoids confined spaces will see more consistent upkeep.
Installation Complexity and Instructions
Installation complexity affects whether you can fit the catch can yourself or need professional help. Clear, vehicle-specific instructions and included hardware reduce install time and the risk of mistakes. Consider whether the kit requires cutting, drilling, or rerouting unrelated components, which increases labor and potential for errors.
Good documentation should show hose routing, torque specs for brackets, and troubleshooting tips. Kits that come with labeled fittings and a simple parts list make assembly and future maintenance less stressful.

FAQ
Will an oil catch can void my Scion tC warranty?
Adding an aftermarket catch can does not automatically void a vehicle warranty. Warranty coverage can depend on whether installation directly causes a failure. Keep records of the installation and use professional service if you are concerned. If a component fails, the manufacturer may require proof that the failure was unrelated to the catch can.
How often should I drain the catch can on a Scion tC?
Drain intervals vary with driving style and engine condition but often range from a few hundred to a few thousand miles. Inspect the can regularly during the first weeks after installation to establish how quickly it fills. Units with sight tubes or clear indicators make it easier to determine the right maintenance schedule for your driving habits.
Can I install a catch can myself?
Many catch cans are designed for straightforward, do-it-yourself installation using basic hand tools. Choose a kit with clear instructions and included mounting hardware if you plan to install it yourself. If the kit requires cutting hoses or modifying mounting points and you are unsure, professional installation is a sensible option.
Will a catch can affect engine performance or drivability?
A properly installed catch can should not negatively affect drivability. It intercepts oil-laden vapors before they reach the intake while allowing crankcase ventilation to continue. Ensure fittings are tight and hoses are routed to avoid kinks or leaks, which could otherwise affect vacuum behavior.
Do I need to service the internal baffle or filter?
Some catch cans have replaceable or cleanable internal elements. Check the manufacturer's guidance, but routine inspection and cleaning are typically enough to maintain performance. Easily serviceable designs reduce long-term maintenance effort and help the can continue separating oil effectively.
Are there any downsides to installing a catch can?
The main tradeoffs are added maintenance and the need to monitor for leaks or loose fittings. Installing a catch can introduces another component to service, and poor installation can lead to vacuum leaks. When chosen and installed correctly, the benefits in reduced intake contamination typically outweigh these considerations.
Conclusion
Choosing a Scion tC oil catch can is about balancing effectiveness, durability, and ease of installation. Prioritize fitment and mounting options that suit the tC's engine bay, durable materials that resist heat and corrosion, and a separation design that is serviceable for routine maintenance.Accept that better separation may mean slightly more complex internals, while simpler units might require more frequent draining. Focus on secure hose connections and clear installation instructions to reduce the risk of vacuum leaks and to make long-term upkeep straightforward.
