Description

The Chrome Push In Breather 2-3/4in Dia 1in Neck is an essential component for any serious engine builder or hot rodder looking to manage crankcase ventilation efficiently. Designed for custom engines, race applications, and modified street builds, this breather serves a critical function: it allows accumulated crankcase gases and vapors to exit the engine safely while preventing oil mist from contaminating your intake charge. Whether you're running a carbureted small block, LS swap, or vintage V8, proper crankcase management directly impacts engine longevity, oil consumption, and overall performance reliability.

This push-in style breather features a 2-3/4-inch diameter head with a 1-inch neck that accepts standard crankcase tubing, manufactured from durable steel and finished in polished chrome for both durability and engine bay aesthetics. The push-in design allows for quick installation into a 1-1/4-inch hole, making it compatible with most custom valve covers, timing covers, or block adapters without complex threading or modifications. Racing Power Co-Packaged engineered this breather with internal baffling to separate oil vapors from air flow, ensuring minimal oil carryover into your carburetor, fuel injection system, or catch cans—a critical detail for maintaining clean combustion and preventing fouling.

Ideal for restomod builds, vintage racing, custom engine swaps, and any application requiring factory-free crankcase ventilation, this breather pairs excellently with remote oil catch cans, PCV systems, or atmospheric venting setups. The compact 2.6 x 5.85-inch profile ensures fitment in tight engine compartments while the chrome finish resists corrosion and complements traditional hot rod aesthetics. Installation is straightforward—simply match your valve cover or adapter hole to the 1-1/4-inch specification, insert the neck, and secure with the mounting hardware of your choice. For street applications, pair it with a quality catch can; for race engines, route it to atmosphere or integrate it into your custom PCV strategy.
