Description

EC 280 Billet PCV Valve – 3/4"-10 Thread for Briggs Flathead & Clone Racing Engines


The EC 280 Billet PCV Valve is a precision-engineered upgrade for managing crankcase pressure in high-performance flathead Briggs & Stratton engines—specifically designed for use with Burris billet side covers and compatible OHV engines like the Ghost 212 and Wildcat 240.


Key Features & Benefits

  • CNC-Machined Billet Aluminum Housing
    Built from high-quality aluminum, this valve eliminates the plastic components found in stock or budget PCV systems—making it ideal for methanol-fueled engines that degrade plastic or rubber parts.
  • True One-Way PCV Function
    Features an integrated internal check valve to allow pressure to escape the crankcase while preventing outside air or contaminants from being drawn in during engine vacuum pulses. This maintains consistent internal pressureand avoids oil contamination or pressure fluctuation.
  • Race-Ready Crankcase Management
    On high-RPM or modified engines, proper crankcase pressure control can improve ring seal, reduce blow-by, and stabilize oil control under demanding racing conditions.
  • Fuel Compatibility
    Methanol safe. A must-have for methanol-fueled flathead and OHV karting engines.


Fitment & Compatibility

  • Thread Size: 3/4"-10 (coarse thread)
  • Direct Fit For:
    • Briggs Flathead with Burris or billet side covers
    • Ghost 212 (when using upper oil fill location)
    • Wildcat 240 (when using upper oil fill location)
  • Recommended For:
    Performance-built OHV and flathead engines requiring precise crankcase venting—especially those running high compression, methanol, or extended RPM ranges


Why You Should Use a Real PCV Valve

Many racers rely on basic open vents or fittings without check valves. These allow air to move in both directions, disrupting crankcase pressure regulation and potentially pulling contaminants into the engine. The EC Billet PCV Valve only allows pressure to vent outward, promoting consistent oil control, better sealing, and engine longevity under race conditions.
