That supports what instinct was telling me. So, anywhere upstream of the butterfly should work? I'm running three 1-barrel throttle-bodies on my p-port 3-rotor. If I understand you, I should hook the check valve for each rotor upstream of the respective TB butterfly, correct?

you need the injection check valves hooked up to your intake plenum. T= he=20 oil intake only works with the pressure difference between the combustion= =20 chamber and the plenum during the intake cycle. The check valve prevents oi= l=20 from being pushed into the vacuum lines by reverse pressure fluctuations. <= /div>
As far as the control lever is concerned, you have a good plan. You ma= y=20 want to make the lever position adjustable so you can set the oil consumpti= on to=20 a level that makes you and the engine feel good.
FWIW
