a welsh plug is a plug in the side of the block and the heads. these fill the holes left after casting.they actually allow the sand to be removed that is used during casting so as you have a hollow block which allows for the water jackets. in the USA these welsh plugs are called freeze plugs. they really do not stop the coolant from damaging the block if coolant freezes they are specifically to block the casting holes
