I made the aluminum block that mounts on the oil filter pad. A chunk of aluminum, a hacksaw, a drill and pipe taps is all you need. A die grinder helps. Buying one ready made is nice too.

I tapped mine for oil pressure and oil temp sensors, but I could go back and feed the oil supply to the engine (as per Kevin's pic).

I used a metric to JIC (aeroquip) fitting in the block, then a sweep elbow (same as kevins pic). It clears the Breese mount without problem and has less flow restriction.

I also have rotor oil jets and the oil bypass pellet is replaced with the blocker piece. The idle oil pressure is a little low when warm, under 30 PSI with 10W30 oil. I'll probably use a more viscous oil when I go to higher power testing, and flight. I have a drum of Delvac 1240 that might be a good choice. It's a low ash oil intended for ported 2 stroke diesels. It's intended to leave minimum piston deposits and reduce ring wear in ported 2 strokes. So I think it would work with rotary engines. Mono weight oils supposedly have superior film strength....although synthetic oils are better yet.
