We'll be doing a fair bit of work this wkd on my Milano 2.5. I've noticed quite a bit of oil on the inside of the intake flex hose, likely due to blow by from the air oil separator. We will soak it in carb cleaner this wkd, but I'm wondering if I'd create an air leak by installing an old school oil breather and plugging the vacuum line on the intake flex hose. Environmental concerns notwithstanding, has anyone else faced this issue and done something similar? My idle is a bit rough with newish plugs, due to other issues perhaps but likely the air oil separator issue is contributing. No noticeable blue smoke out tail pipe and recently passed NJ emissions.
