I’ve been hearing conflicting opinions regarding whether to put Permatex or other silicone sealer on the outside of replacement seals when they are installed. Some argue that replacement seals with colored outer surfaces already have a solid sealer painted on, so you shouldn’t have to put any more on. And they say that extra silicone makes it harder for the next guy who has to replace the seal.
Others argue it is ‘insurance’, reducing the chance of premature seal failure by helping to hold the seal in place and helping to reduce the chance of fluid tracking along the metal contact surface. The latter might have been marred a little by seal removal tools when the old seal was removed.
I’m asking for an opinion poll of what you guys do….
