What kind of oil filter does a 1975 Shovelhead have?
Bought a 1975 Shovelhead a while back from a very shady character and among other things, when you start the engine, it starts puking tons of oil all over the floor. There is a braided metal line about 6-8″ long with a small filter on the end of it. Looks like a crank case breather line, on the right side of the engine.

Where does the oil come from in a Harley Davidson?
Top breathing engines breath, or vent, through the top breather bolts which are threaded into the heads of a Harley Davidson motor. The air inside a motor is saturated with oil. It exits through the breather bolts and into the airbox where the air is filtered and the oil is captured in the air filter.
