Dry Sump Breather Tank 1-1/2in Clamp On

The Dry Sump Breather Tank 1-1/2in Clamp On from JOES RACING PRODUCTS is a critical component for high-performance engine builds where oil management directly impacts reliability and longevity. Whether you're running a dedicated race engine, a heavily modified street machine, or a drag-strip competitor, this breather tank serves as the backbone of a dry sump system—preventing oil vapor blowby, crankcase pressure buildup, and catastrophic seal failure that can wreck a freshly built engine. Designed for mechanics and engine builders who understand that controlling crankcase emissions isn't optional on forced-induction or high-RPM applications, this clamp-on tank integrates seamlessly into aftermarket configurations where vacuum and positive ventilation must be actively managed.

The 1-1/2 inch clamp-on design allows flexible mounting on custom intake manifolds, engine blocks, or frame rails without requiring permanent boss drilling or welding. The tank captures oil mist and condensed vapors expelled from the engine, allowing liquid oil to drain back to the pan while directing filtered air safely away from the crankcase. This separation principle maintains critical vacuum levels, reduces atmospheric contamination entering the engine, and extends component life by preventing oil starvation and ring flutter common in naturally aspirated or supercharged applications operating at sustained high RPM. At just 1.26 pounds and compact 7.9 x 3.55 x 14 inch dimensions, the breather tank fits tight engine compartments without sacrificing flow capacity or requiring extensive custom fabrication during installation.

Professional engine builders, circle-track competitors, and street rodders rely on this breather tank when upgrading stock crankcase ventilation systems that cannot handle boost pressure or continuous high-load operation. Installation pairs with -12 or -16 hose routing from the engine's PCV source and differential valve management, making it essential for any dry sump retrofit or modern LS, small-block Chevy, or custom engine platform conversion. Verify hose connection sizes and vacuum pump specifications before ordering to ensure compatibility with your existing system architecture and flow requirements.
