I have used the orange Permatex high temp, sensor safe RTV Silicone. Clean all of the surfaces, including O ring with acetone so that they are totally oil free. Put a tiny line of Silicone on all mating surfaces (one side only) with a tooth pick, and wipe off the excess after tightening down. Works great, but a bit difficult to remove.
