generally what i do with cockers is clean it after a tournie, a little bit of vaselene on the bolt orings (just the orings), disconect the air system and put 2 drops of oil in the asa (NOT the fill nipple of the air system like some fools) and thats it.
the eblade sear will need lubing now and then but not every use.
as for the hammer i have always run that completely dry, if you start putting oil in there it does nothing but form a grining paste with any grit that gets in
