This is a bad idea. Engine oil, clean or not, has no place in the intake tract of an engine.
What "valve" do you want to keep "wet" and why? If the intake valve requires a coating of oil to seat properly, something else is wrong, and using oil in this manner is only a stopgap measure at best, and will lead to bigger problems down the road at worst which will be more expensive to deal with.
Can you please give a source and rationale for this suggestion of yours?
