Where is the vent on a V-twin dipstick?
The port on the engine case is plugged and the port on the oil spout is fitted with a hose that runs under the back bone and down the front down tube to the catch can. Running a breather set up out from behind the air filter will do the same thing as venting the out tank, correct?
How does a vented dipstick work on a Moco?
The MoCo changed this with one of the oil pump upgrades, to make the pump suck through the crank bearing, to reduce the amount of oil left in the crankcase. The oil pan vents to the cam chest through a bulkhead passage. The design of the internal breathers allows vapour to vent out of the head area, but it does not allow it to return.

Pinch of the vent line between the engine case and oil tank and then rev the engine to a high idle. The oil cap will pop off because the pressure is not being relieved. If the EPA were not involved, the oil tank and engine would have separate venting systems.
What do Feuling vented dipsticks do in an oil tank?
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 into the oil tank.
What causes the oil cap to blow out?
Engines with a PCV (Positive Crankcase Ventilation) valve that is clogged can build up internal pressure and cause a cap to blow off, unless the cars computer is smart enough to stop the engine. A pressurized crankcase can in time literally blow/pump all of your oil out resulting in a seized motor.
How does a blow by dipstick work on a Harley Davidson?
Blow by is pressure that is forced past the rings and cylinders, pushed into the crankcase and then forced into the oil tank. FEULING ® dipsticks help remove this unwanted pressure through a (CVS) Crankcase Ventilation System.
