Description

The CUSCO Street Oil Catch Tank is a functional engine performance and maintenance component designed to protect your engine by separating oil, fuel vapors, and contaminants from the positive crankcase ventilation (PCV) system’s blow-by gases. By capturing these impurities in a dedicated 0.6L tank and returning only clean vapor to the intake, it helps maintain optimal combustion efficiency, prevent carbon buildup on intake valves, and safeguard engine power and reliability over time.

Product Highlights

🛡️ Protects Engine Performance & Longevity
Intercepts oil mist, fuel vapors, and moisture from the crankcase ventilation system before they can re-enter the intake. This prevents:

• Reduced octane rating of the air-fuel mixture.

• Carbon deposits on intake valves and throttle bodies.

• Potential detonation (knock) under high load, especially in turbocharged engines like the GR Yaris.

🔍 Easy Monitoring & Maintenance
Features a built-in oil level gauge, allowing for quick visual checks of accumulated fluid. This makes routine maintenance simple and helps in early detection of excessive blow-by, which can be an indicator of underlying engine wear or issues.

🔧 Complete Bolt-On Kit with Suction Return

• Includes everything needed: 0.6L tank, mounting bracket, suction return kit, and hoses (Φ15mm inner diameter).

• Bolt-on installation with an estimated time of 1.0 hour.

• Compatible with the GR Cold Air Intake Duct, ensuring fitment with popular intake upgrades.

⚙️ Optimized for Street & Performance Use
With a practical 0.6L capacity and street-oriented design, it effectively manages blow-by during daily driving, spirited runs, and track days without requiring frequent emptying.

* Toyota GR Yaris RS grade model 5BA-MXPA12 (FF) cannot be installed.

Installation & Usage Notes

✅ Professional Installation Recommended
While a bolt-on kit, proper routing of hoses (away from heat sources and moving parts) and secure mounting are important for long-term reliability and safety. A professional install ensures a clean, functional setup.

⚠️ Regular Maintenance Required
Periodically check the oil level gauge and drain the accumulated fluid as needed. The frequency depends on engine condition, driving style, and track use. Do not allow the tank to overfill.

🏁 A Smart Supporting Mod for Tuned Engines
Especially beneficial for modified or high-mileage engines where blow-by gases can be more prevalent. It’s a simple, cost-effective way to protect your engine investment and maintain consistent performance.
