RTV stands for "Room Temperature Vulcanizing". Comes in a tube, and has at least 3 colors- blue, red, and black, indicating useful temperature, and whether or not it cures in the presence of air, or the absence of it. It is designed to take the place of gaskets, or to skim coat paper ones. Works great, except on the cork gaskets. You can find it at an auto parts store. -------------------------------------------- On Wed, 6/25/14, Sacha wrote: Subject: Re: RotaxEngines-List: air entering fuel system on suction side - or is my Pierburg electrical pump broken?

I used some red stuff which I thought was for engine gaskets. I think Motorsil was the brand. Anyway just to be sure I'll remove it as it serves no useful purpose.

Are they to be confused with silicone seal? john h Rock House, Oregon ________________________________ Message 3 _____________________________________ Time: 07:37:15 AM PST US From: william sullivan Subject: RE: RotaxEngines-List: air entering fuel system on suction side - or is my Pierburg electrical pump broken? John- I know that one is fuel resistant- red, I think. Pretty sure it's silicone seal. My experience is very limited, so I only remember some of the cautions with the stuff. I had a friend who bought a used Cadillac with a freshly rebuilt motor. The cork oil pan gasket dissolved, and cost him an engine rebuild. -------------------------------------------- On Thu, 6/26/14, John Hauck wrote: Subject: RE: RotaxEngines-List: air entering fuel system on suction side - or is my Pierburg electrical pump broken?

Had used silicone seal to seal the vent hole in the Ken Brock seat tank filler cap so I could convert to a vent that exited the bottom of the aircraft and prevent fuel from dumping inboard should I go upside down on the ground again. Tiny balls of silicone seal effectively blocked the valves in the squeeze bulbs we used to use back then. john h mkIII Rock House, OR ________________________________ Message 5 _____________________________________ Time: 08:38:29 AM PST US From: william sullivan Subject: RE: RotaxEngines-List: air entering fuel system on suction side - or is my Pierburg electrical pump broken? I seem to remember that silicone seal (RTV) was being used at automotive factories to replace a lot of gaskets, some time in the 1980's. Worked great for differential covers, etc. The biggest problem I ran into was that we weren't sure where, or what type, to use. Best bet is to bring your glasses to the auto parts store and read all that very tiny print on the packages. Where I worked, the most common type was blue- we called it "Blue Goo". Stunk like hell, and hardened in the tube if it sat around for a while. Maybe Roger or somebody with a lot more practical knowledge can chime in on this. I was in truck equipment, not automotive. -------------------------------------------- On Thu, 6/26/14, John Hauck wrote: Subject: RE: RotaxEngines-List: air entering fuel system on suction side - or is my Pierburg electrical pump broken?
