Feuling Vented Dipsticks

for Milwaukee Eight and Twin Cams

FEULING billet aluminium dipsticks vent/breathe excessive crankcase 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. 

Feuling vented dipsticks screw into the factory oil fill spout as a stock replacement part. These breathing dipsticks remove unwanted build-up of blow-by pressure in the oil tank.

Blow-by is pressure that is forced past the rings and cylinders, pushed into the crankcase and then forced back into the oil tank. Feuling dipsticks help remove this unwanted pressure through a Crankcase Ventilation System (CVS). 

Test results show a decrease in engine oil sump levels, more freely/smoother revving engine, increased MPG and decreased blow-by.
