  • Whether you're building an engine from scratch, rebuilding an engine that has been thrashed or updating from the OEM plastic breather, we recommend using one of these top quality steel breather valve and gears
  • The stock plastic breathers are known for their terrible distortion and can easily be upgraded to one of these
  • All Jim's breathers are of the late style slotted design
  • All breathers listed are designed to be used with Late 1979/1982 steel breather shims
  • See the engine section for breather shims
  • Available in standard diameter or +.030 outside diameter
  • The +.030 is designed to repair gouged out breather holes and will require machine work
