Hello, I need information about rotary valves. I don't know anything about that system, but I need to know a few things for a project, so i need your help.

- Are the ducts in the covers for lubrication?

- If they are for lubrication, are they lubricated with the mixture or with oil?

- Does the oil or mixture that passes through the ducts end up in the sump during intake?
