Would it be possible to make a full overview of the Model A engine and its mating surfaces in terms of gaskets and sealants. I am usually getting confused by all the solutions mentioned by members online ... most of them diverging heavily from Les Andrews recommendations.

To mention af few areas of interest to me

1. Valve cover
2. Water inlet on engine block.
3. Water outlet on head ... also called gooseneck
4. Timing gear cover
5. Water pump to head surface
and so forth...

People mention

cork gaskets
thin paper gaskets
thick paper gaskets
copper gaskets
asbestos gaskets
or NO gasket at all. Instead you use a gasket compound
etc etc

and all these gaskets can be installed

dry
soaked in oil/grease
gasket compound on one side
gasket compound on both sides

out of the gasket compound I have narrowed it down to

compounds that become hard after curing
compounds that stay soft after curing. For instance RTV silicone
compounds that never cure and have a tacky feel, for instance hylomar

Now, I would be very pleased if I could use either RTV silicone or Hylomar on ALL surfaces WITHOUT any gasket at all. Is that possible? That way I would only need to have one single tube that fits all. If that is not possible, could someone make a full list of mating surfaces combinations? It would be highly appreciated.

Nobody with any information on my topic? :-)

Most properly prepared gasket surfaces only need what the factory used ---nothing

then it comes to what you like to use, and what you want to happen if you need to take it apart ---some people like to have a project and spend alot of time scraping the old gaskets off so they use drying sticky sealer on both surfaces, some like to reuse gaskets so they use grease both sides, some like to stick a gasket good on one side, but make the other side come off, glue on one side, grease on the other, some don't like to scrape off the gaskets that were glued on both sides, they use Hylomar to seal the broken pieces

With gaskets I use just a smear of grease on both sides. ( unles manufacturers/suppliers spec says otherwise)
Because some of the metal components we're using are very ancient- sometimes pitted and sometimes slightly warped on all gaskets (other than the head gasket as stated) I generally smear with a light layer of Blue Hylomar on both faces of the gasket.

I use grease on both sides. Except on the oil pan where I use compound on the bottom side and where the gasket meets the string and grease on the top side. I find this helps hold the darn thing in place while I install the pan.
