put it in park [on level ground], lift the hood, and with the parking
brake OFF, rock the car back and forth. you'll see the motor move and
the cracks should open up to be visible. if you can get an angle to see
them. if not, you might need to have an assistant help you rock the car
while you poke about with a mirror.

Should the motor mounts be totally replaced? Or is it just a case of
them loosening up over the years?

replaced - the rubber breaks apart. usually you can get away with just
the rear and front [if yours has a front]. also check for gotchas like
bent exhaust touching chassis, loose heat shields, etc.
