Both could be true though. Just because a robot does one bit doesn't mean the rest isn't done by humans.
Still, I don't understand how hard it would be to develop a pre-formed seal a la BMW. With all the issues these engines have (even though they're not as bad as we sometimes make 'em sound), one would think Subaru would have saved money in the long run.

this came up in another similar thread a while back. subaru uses a thin sheet metal oil pan that easily deforms. the block is also multiple separate parts that bolt together across the oil pan seal.
so to use a gasket would require a thicker oil pan. not difficult. but also, the block mating surfaces would need to be lapped after the block is assembled to ensure a perfectly flat surface for the gasket to seal against. which is really where a sealant works better than a gasket.
