Well, my idea is to tap the oil pan (at a level that in the event of a rupture, will not starve the engine of lubricating oil (i.e. using a stand off tube))and use an electric pump (which can be turn on or off)to circulate oil to the heating coil in the nose.
I've seen pump that can circulate 4 to 8 gal/pm easily, which I think will be ok for heating. I've also planed for a heat exchanger (coolant/oil) to help keep oil temps higher.
Do you guys see obvious faults/problems with such a setup?

If you are going to use a Mazda rotary, the oil pressure is to high and pulsating to use! Unless you use another pump to pump it out of the oil pan to the heater. The engine oil pump will eat up most every flexible line or coil you might use.
