[200q20v] Was Reusing gaskets; added slight eS2 update

I'm not familiar with all of the gaskets that you have been discussing, but
in general, gaskets can be both needed and not needed in different
applications. If you are using a very thin gasket, then using a small amount
of RTV on the surface seems to work well, especially to allow the RTV to set
up (assembly aide).

I use to work in a pump repair facility (medium to high energy pumps up to
4,000 psi discharge pressure) and we found that sometimes using no gasket
was better then using a gasket (and non RTV). However, this was on a surface
that was machined to less than 0.001" flat and had a lot of bolts holding it
in place.

Answer to the question? Who knows?
