E32 heater valves disassembling + cleaning

My collection of pics on the German 7-forum
http://www.7-forum.com/forum/24/heiz...gen-44167.html

These, BTW, show heater valves where some 'magic' coolant leak seal stuff was used.
After you have seen the pics you probably will never use such stuff again, it does not only clog heater valves but also other parts inside the engine, I even found the stuff clogging partly a heater core in a parts car. Do not know the brand name of the super leak stopper which was used, but just to show you that some products are not really that good to seal a leak. My opinion, if there is a leak, repair the leak, but not with 'magic' stuff.
