Fabricated Alum Oil Catc h Tank Breather 1.0 Pint

The Racing Power Co-Packaged Fabricated Aluminum Oil Catch Tank Breather is a bolt-on separator designed to prevent crankcase vapors from entering the intake system while managing excess pressure in high-performance engines. This 1-pint aluminum breather tank offers a compact solution for engines that generate significant blowby, particularly in naturally aspirated or modified builds where factory PCV systems prove inadequate.

Measuring 3 inches in diameter by 7.5 inches tall, the tank features dual 1/2-inch hose barb inlets for flexible routing from the crankcase. The aluminum construction provides durability while remaining lightweight—critical in performance applications where unsprung weight impacts handling and fuel economy. The natural finish resists corrosion better than bare steel, making it suitable for long-term under-hood duty. At 0.75 lbs, the minimal mass avoids performance penalty while delivering reliable vapor separation.

This breather tank is engineered for street-driven performance cars, race engines, and high-horsepower builds that require effective crankcase management. It integrates easily into existing catch tank setups or serves as a standalone solution for direct crankcase ventilation. The 1-pint capacity accommodates typical oil carryover from moderate blowby; users operating in sustained high-load conditions or with extreme ring blow may benefit from larger capacity designs or multi-stage separation. Racing Power Co-Packaged delivers this tank as a single unit ready for immediate installation, making it accessible for enthusiasts managing their own engine work.
