pat are the cam covers a single peice or 2 peice like a 4age? you could swap them around..
or run the quads up side down?
guestimation on the 20v PCV is 10mm i think if the beams one is bigger i dunno, maybe pirtek or something can make a bent one?
as for a catch can look at what ORIDO has for sale its a pretty neat set up where the JDM washer goes.
