That is a downside but if you remove the filter elements entirely and have exhaust gasses pull the crankcase gasses out then you will have no issues at all. I was thinking about doing it that way but the benefit I would get would be suffice to do the work to get it routed because I would have to redo the exhaust in order to get enough pressure to pull the gasses out.
