Abstract
An engine comprises a cylinder head at least partially defining a dry valley and a cover secured to the cylinder head. The cover defines a first aperture. A boss extends from the cylinder head toward the cover. The boss defines a second aperture. A fastener extends through the first aperture and at least partially through the second aperture to secure the cover to the cylinder head. The fastener defines a passage to fluidly connect the dry valley to an exterior of the engine.
