I am ready to replace my valve cover gasket and have one question. BMW states to put Drei Bond 1209 in half moon areas of the valve cover. I've read here that most people do not put anythig just the rubber gasket. What else can be used in place of Drei Bond? I was looking at all sorts of gasket silicone sealants but I am little confused. I bought Permatex High Temp Rec RTV Silicone Gasket maker but I am not sure if this will work. Thanks!
