Does anyone know what oil filter adaptor works on an O-320 and an RV-4. Apparently this replaces the Vernatherm housing. I have found out that there is a pressure filter in that housing that is supposed to be checked and cleaned every 25 hours. To get to mine I have to remove the vacuum pump and to remove that I have to remove the right mag. What a pain. I also noted that above the vernatherm housing and slightly to the right (looking forward from the pilot seat) is the mechanical take-off for my tach. So, I've looked at several online. The one that looks nice looks like the filter is almost vertical tilting maybe slightly to the left side of the airplane. The instructions say to puncture the top of the filter when you are ready to remove it. The oil drains down and you don't get oil everywhere. Nice if I have the room. Otherwise I have to go with one that the filter goes straight back.
