Breathers for Valve Covers
Valve cover breathers serve as a critical component in the engine's ventilation system. They are designed to allow the expulsion of gases from the crankcase, promoting efficient engine performance and reducing harmful emissions. These breathers help to maintain the pressure balance within the engine, preventing the buildup of excessive pressure which can lead to oil leaks or damage to the engine's seals and gaskets. Available in various styles and designs, valve cover breathers not only enhance engine functionality but also offer an opportunity to customize the engine's appearance.
Rocker Cover Breathers
Rocker Cover Breathers, often synonymous with valve cover breathers, play a pivotal role in the engine's positive crankcase ventilation (PCV) system. These components are mounted on the rocker covers and are essential for venting out unwanted gases from the engine's crankcase. By doing so, they help in reducing the engine's internal pressure and minimizing the risk of oil leakage through the seals. Rocker Cover Breathers come in various designs, including those that can directly replace the factory breathers, offering improved ventilation and a touch of customization to the engine bay.
SBC Valve Cover Breathers
SBC (Small Block Chevy) Valve Cover Breathers are specifically designed for the iconic range of Chevrolet small-block engines. Known for their durability and high performance, these breathers match the unique requirements of SBC engines, ensuring optimal crankcase ventilation. They are available in various finishes and styles, from classic to contemporary, to complement the aesthetic of any SBC engine while providing effective expulsion of blow-by gases. Installing high-quality SBC Valve Cover Breathers is crucial for maintaining the legendary performance of Small Block Chevy engines.
Clamp-On Breather Filters
Clamp-On Breather Filters represent a universal solution suitable for a wide range of engines and valve covers. These breathers attach directly to the valve cover vent tube, providing an efficient filtration system for the expelled gases. The filter element within traps dust and debris, ensuring only clean air is released into the atmosphere. This not only helps in reducing environmental pollution but also protects the engine by preventing the ingestion of particulate matter. Clamp-On Breather Filters are easy to install and are an excellent choice for those looking for a simple yet effective way to enhance their engine's ventilation system.
