Probably only a dealer parts department or a good independed mechanic will know what they are, they don't need to be replaced very often.

The oil separator on the 60x engines is in the valve cover, not the air filter housing or separate. Nice little curved tube for the oil return so it won't blow back. Takes up quite a bit of the space in the valve cover, the camshaft is centered on the head/valvecover line.

I will refrain from making political comments.
