I worked at a factory once that employed illegal migrants from Africa, they can learn to read a calipher and push the start button on a CNC and move crates of metal cubes. Programmers would set up a machine and it will run for the day. At a factory dedicated to making the same parts always you need less programmers because you are always doing the same parts.
Some engines parts of course require special coatings or ceramic parts and hardening. Maybe they can do the block there and ship the parts for treatment, its harder to do coatings and heat treatment right in a modern light-efficient engine.
