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.

Bill
Thank you. I'm not sure what RTV is. 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 all RTV sealants fuel safe?
Are they to be confused with silicone seal?

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.

Back in 1987, silicone seal caused a low power situation
that put me into the Sebring High School football field.
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.

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.
