I don't appove of the fashion of using bloody silicone muck all over engines, as the excess can ouze out and break off, travel though out to lubriction system and block off something important. I've seen it happen!
On cork gaskets I use permatex No. 3 aviation grade non-hardening gasket sealer.
I paint it onto the gasket with the brush attached to the lid of the bottle.
As it's non-hardening you can get the gasket and sealant off with realative ease when next you need to pull the assembly apart again......no need for the jack hammer!https://www.permatex.com/products/gasketing/gasket-sealants/permatex-aviation-form-a-gasket-no-3-sealant-liquid-3/
I see that there are some health warning on this stuff now
Carciongenic and reproductive, so wear gloves etc and don't paint it on your pecker, but why would you.....it's non-hardening!
