I have always wondered how much crankcase breather vapor and oil is going into the throttle body. I made a temporary breather experiment to test it out. After 1000 miles Id guess about 1/3 to 1/2 a teaspoon of oil was prevented from entering the motor in the 1000 mile / 1 month time frame. Im not sure if that amount of oil is a problem or not inside the throttle body and combustion chambers but, it longer spews oil in the air cleaner.
Im going to keep it installed for now and find a more appropriate catch can.

tooooooo many variables affect this experiment. so there is no solid conclusion.

I'd bet that you have more than just 1/2 teaspoon going into the container. The problem is that most of the oil passes right through as mist. You need a bigger container,, Some filter material can help to catch the mist..
