DRAIN IN BOTTOM

Group A breather separator system is an aftermarket engine modification, primarily associated with highly tuned Ford Sierra and Escort RS Cosworth models equipped with the YB engine. It is designed to manage excessive crankcase pressure and oil mist in modified, high-performance engines (often 400hp+). 
Purpose and Function
When an engine is modified for increased power and boost, there is an increase in “blow-by” (combustion gases leaking past the piston rings). This causes the crankcase to pressurize, which can lead to: 
  • Increased oil consumption.
  • Oil being forced past gaskets, seals, and turbocharger seals, causing leaks. 
The Group A system addresses this by:
  • Separating oil particles from the air/oil vapor using internal baffles.
  • Returning the separated oil to the engine sump below the oil level to prevent upward pressure.
  • Venting the cleaner air, either to a separate catch tank or to the atmosphere/air filter housing. 
Key Features
  • Design: The design is based on systems used in Group A Touring Car racing to handle serious levels of blow-by and oil surge.
  • Configuration: It typically includes a fabricated aluminium oil separator (often a 3-port design to vent from both sides of the crankcase) and associated hosing and fittings.
  • Compatibility: While originally for the Cosworth YB engine, Spec R and other manufacturers have developed similar systems for other high-performance vehicles like the Mk2 Focus RS.
  • Benefits: It significantly reduces oil consumption and keeps the engine bay cleaner from messy oil vapor, which is a common issue for high-powered Cosworths.
