I just picked up a 1985 2F to replace my F that threw a crank bearing. I have been pulling all the external parts off of the block, cleaning and re-tapping holes that were really full of crap/dirt etc... and getting ready for some paint. I pulled off the water pump and cleaned it up prior to re-installation. I pulled the back plate off and it had a fair amount of crap in it. I cleaned it out but my question is this, Is there a gasket that goes between the backer plate and the housing? It almost looked like someone had put in "right stuff" gasket sealer but I am not sure as there was too much crap in there. Gasket, Sealer or no??? Searched the site and could not find a clear answer. Thanks for the help.
