It's the reason I can remove my Subaru's top-mounted, base-down filter without making any mess. Makes me feel good when I see that a "used-up" filter has a good-working ADBV.
Can or can't? So the filter is empty when you remove it?
My Tacoma has the filter mounted vertically with base down. If I don't punch a hole in the dome end to drain it, it'll puke oil upon removal.
Can - am able to. There is some that will drain as you remove the filter, but it is contained, by design. The filter itself doesn't leak much upon removal. The filter is heavy with oil when I put in on my drain pan. When I check however long after (weeks, usually), it feels much lighter and emptier. The filter isn't really even close to perfectly hydro-locked, so it will drain eventually.
