If yes ...where is it located and how often is it supposed to be changed?

Thanks.

No valves, but each valve cover has a vent on top with a tube, running to the intake in the rear, connected to it. The hole to the tube is actually a pinhole and can clog from sludge over time. Also, the tubes harden with age and should be replaced (mine at about 10 years).
