Hemi PCV & Oil Separator Guide: Blow-By on SRT Engines

Blow-By on Supercharged Hemi

Cylinder pressure on Hellcat and Trackhawk engines forces more crankcase vapors through the PCV system than a stock V6. Over time, oil mist coats intake paths and can contribute to carbon on valves (though direct injection has separate concerns).

PCV Inspection Points

Replace PCV components with OEM equivalents unless running a proven aftermarket separator system.

  • Check PCV hose hardness and oil saturation
  • Inspect valve cover grommets for leaks
  • Monitor oil consumption between changes
  • Consider catch can on tracked cars
