Heater pipe replacement part # 94810606910

[JSP]

Does anyone have any step by step info on how to replace the plastic heater pipe with the aluminium pipe part # 94810606910. There was an attempt made on a Rennlist posting but no conclusion. The 6 Speed site shows the before and after, but very little about the how, and it appears that the engine was dropped anyway to replace the rear distribution manifold. I don't want to drop the engine, that's out of the question, so any tips would be welcome. I have removed the intake manifold and fuel rail to replace the starter for an intermittent partial crank starter issue. Found an abandoned mouse nest in there and the PCV vacuum control wire and a knock sensor wires were completely chewed through and the wires on another knock sensor were gnawed exposing the bare wire. I have replaced two knock sensor plugs and spliced the vacuum valve wires by soldering and covering each conductor with heat shrink tubing and then covering both with another heat shrink tube and then wrapping them with high temperature glass cloth tape and the wrapping them again with Lakota anti-rodent tape. Since I'm the valley, I want to replace as much as I can within reason;

the starter as mentioned as well as the knock sensors, the heater pipe 94810606910 and the plastic coolant vent pipes, the water pump and thermostat. I also replaced the manifold gaskets as there was signs of vapour staining around a couple of the intake ports. It's a 2008 CTT with over 190000 km, the body and frame are in excellent shape and the it runs well, no MIL and there were no codes on my Bluedriver scan. The previous owner followed Porsche's guidelines and had the oil and filter changed at 20,000 km and once a year intervals at the Porsche dealer which probably led to the stretched timing chain and cracked and deteriorated chain guides which I got repaired with assistance of an aftermarket warranty shortly after I purchased it at 180 000 km. I change the oil at 5000 to 7500 km intervals or once a year which ever comes first, I don't drive it all the time as I have a winter beater and a summer beater too to run local errands.
