there is a pipe which, is located about an inch higher and about three inches to the right of the actuator,(also next to a large engraved number) is it a oil feed of some sort (it ends in like a kind fuel of conector, a bronse sort of nut and bolt) I ask as i have a small oil leak and not to sure where from it's covered in small amounts the actuator but mainly on the big pipe feed that goes to the air filter and the surrounding vacume lines?
