This is interesting. Four apex seal oil injectors.
In another picture the lines look like they are steel instead of nylon.
Its about time. More engines died from cracked and brittle
plastic apex seal oil injector lines than from all other reasons alone.
The little  air assist rubber hoses can be got to and replaced
as needed.

Another neat thing is all the fuel injectors seem to be in one
line so one fuel rail can be used simplifying the fuel system.
Good news.
