I never understood why #3 runs hotter than the others, maybe it's the fan design. I built that engine for a friend and his family in the '70's for his Westy. They immediately took off for Yellowstone Park, and it blew on a long climb in Montana. They left it by the side of the road, and it was gone when they came back to haul it to a shop. They could not locate it, so they figured it was stolen. They flew home, and got an insurance settlement. A few months later, the sheriff in that county called them to tell them they had picked up the van from the side of the road. They really "impounded" it, because even the insurance company couldn't find it. They did not want it back, lucky for me.
