Feuling Vented Oil Dipstick


  • Billet dipsticks vent/breathe excessive crank case pressure from the oil tank through a PVC style breather consisting of an oil separator system, perforated disc, replaceable filter element and umbrella flapper valve
  • Screws into the factory oil fill spout as a stock replacement part
  • These breathing dipsticks remove unwanted build-up of blow by pressure, all internal combustion engines have a certain amount of blow by
  • Larger cubic inch, worn and or loose ring clearance as well as engines pushed to their limits generally have increased blow by
  • Blow by is pressure that is forced past the rings and cylinders, pushed into the crankcase and then forced back into the oil tank
  • Dipsticks help remove this unwanted pressure through a (CVS) Crankcase Ventilation System
  • Feuling test results show a decrease in engine oil sump levels, more freely/smoother revving engine, increased MPG and decreased blow-by
  • Dipsticks vent/breath excessive crank case pressure from the oil tank through a breather system consisting of a oil separator system, perforated disc, replaceable filter element and umbrella flapper valve
  • Includes two venting styles options to choose from when installing the dipstick
  • Option 1: 1/8" NPT breather vent fitting with internal porous filter element (this option gives a clean look, however it can produce an oil misting/residue out of the element on engines with excessive leakdown/blow by)
  • Option 2: Quick-disconnect coupler fitting with rubber hose and filter element (this option will run any excessive oil misting/residue through the line and into the filter element, however this option does requires disconnecting the fitting in order to check the oil
  • Option 2 is Feuling's preferred option as it breathes more than Option 1
  • For Option 2, Feuling recommends routing the line up the frame rail, up under the seat/abs area then back down along the right side frame rail and the filter element can fit cleanly between the engine/trans matting area on the inside of the lower right frame rail
  • Checking oil level: There are two ways to read the oil level with this dipstick, with the bike on the jiffy stand (FHS) or the bike upright and level (FHU)
  • FHS = FULL HOT STAND: if reading the dipstick with the bike on the jiffy stand you will take your reading from the dimples labeled FHS (Full Hot Stand)
  • FHU = FULL HOT UPRIGHT: when reading the dipstick with the bike upright and level you will take the reading from the dimples labeled FHU (Full Hot Upright)
  • Available in polished or fade-resistant black
  • Made in the USA
