Wow! have you got a problem! The plate looks like it isn't there anymore - all rotted out. I do not think that by just replacing the mortar between the house and the block you're gonna solve anything. AND you say you got wood rot in the crawlspace. to do it right would require jacking up the whole house, chipping out all the concrete, removing all the plate and replacing it with a treated board. then put a sheet metal U piece between the plate and block and drop the house down on top of that. incorporate a flashing that would send water AWAY from the house so it doesn't weep underneath the new plate.
