Boy, that is truly odd. The pipe that runs across the front of the engine is the heater return. The supply pipe is off the left rear side of the head. The returns go through the mono valve, which should be in the compartment with the battery. What could the second pipe be coming from? As for the fan holding system, that was used from the start on the M103 and carried over on the M104. Also odd. This has me scratching my head. Maybe someone else has seen this or can comment.
