Thanks for the flow paths. For lack of a simpler path, I guess I will tie into the heater circuit (always flows). I'd prefer the cooler coolant, but I don't think I'll tap a fitting into the block. Anyway, once N.O.T. is reached, the oil should always be hotter than the coolant leaving the engine, so I guess it won't hurt. I don't really care for dumping extra heat back into the water-pump, tho. Hmmm.
