I'm finally returning to installation of the oil cooler and radiator hoses on a 912iS with oil cooler. One of the first steps with the 912iS is to move the oil return port to the bottom, pilot side of the engine. Instructions and drawings in the Oil Cooler Installation section clearly show the return hose running from the top of the oil reservoir to a return line located at the front of the engine. After lots of head scratching, I'm concluding the Oil Cooler plumbing instructions are "general" and for the 912iS, the return line goes to the fitting on the bottom of the engine. Any comments?
