Closed Crankshaft The 2007 emission regulations require that all engine gas emissions be reduced, including crankcase gas. As a result, we'll be adding a closed crankcase system that reroutes ventilation gases back into the engine for combustion. Some systems will have serviceable filters to collect residual crankcase oil.
  • Crankcase gas is effectively reduced to meet the 2007 emissions standard.

  • Ventilation gases are rerouted back to the engine for complete combustion.
