I am interested to hear from anyone who has the antisplat unit WITHOUT the vacuum to the exhaust (i.e. drain back to the sump). My objective is to reduce oil consumption (in addition to cleaning the belly). Right now, I am using about a quart per 5 hours and am convinced most is going overboard via the breather, even keeping the oil level in the range of 7 qt. It seems in principle the vacuum system would, if anything, increase the oil going out the breather system. Can anyone report whether they have significantly reduced oil consumption with the non-vacuum intallation?
