I installed the breather and two weeks have gone by with NO oil loss. some highway and some city driving. I will continue to monitor. if anyone else is experiencing oil loss and would like to try this so we can get more info please do. what i did was disconnect the hose from the pcv valve and plug it. then get a short piece of hose that will fit over the pcv valve end that you disconnected. connect the other end to the breather. i purchased one for $10 at the auto parts store. the most important thing is that you plug the end of the hose that you disconnected ,i even used hose clamps you do not want a vacuum leak. shawn
