For those of you that run a vac pump, how do you control the oil from coming out the breather? On start up I have 3" of vac & its regulated to 10" of vac, on full rpm. There are 2x lines with baffles that pull the air from the front of the rocker covers. Every run we get maybe a tablespoon of oil from the catch can but it always has about 2x tablespoons of oil dripping off the filter. Can anyone enlighten me on how to stop the mess I have to clean after every run?
