Abstract: A pump housing associated with a vehicle includes a housing body that at least partially defines a pump chamber. The pump chamber is configured to at least partially receive a pump. The pump housing includes a chamber cover configured to be removably coupled to the housing body. The chamber cover includes a mating surface that is configured to contact the housing body when the chamber cover is coupled to the housing body. The mating surface defines a sealing member groove spaced apart from an exterior surface of the chamber cover and a drain configured to fluidly couple the sealing member groove with the exterior surface. The sealing member groove has a depth and the drain has a drain depth that is 45% or less of the depth of the sealing member groove.

Abstract: Vehicles, oil intake systems for vehicles, and methods for manufacturing oil intake systems for vehicles are provided. A method for manufacturing an oil intake system for a vehicle includes providing an oil reservoir having an internal volume with an internal shape including an oil reservoir bottom; determining a selected amount of oil received in the oil reservoir; selecting a maximum positive pitch angle of a first plane of an upper surface of the selected amount of oil in the oil reservoir; selecting a minimum negative pitch angle of a second plane of the upper surface of the selected amount of oil in the oil reservoir; determining a bottom plane at a selected positive distance above the oil reservoir bottom; determining a shape and a size of an oil pick-up tube and of an opening in the oil pick-up tube to locate the opening below the first plane at the maximum positive pitch angle and below the second plane at the minimum negative pitch angle, wherein the opening is defined by a peripheral edge of the oil pick-up tube, wherein the peripheral edge lies substantially within an opening plane, wherein the opening plane has a positive pitch angle of at least half of the maximum positive pitch angle; and fabricating the oil pick-up tube with the shape, the size, and the opening.

Abstract: A valvetrain assembly for an internal combustion engine includes a first camshaft, a first intake cam, a second intake cam, a first cam slide member, and a first actuator. The first camshaft rotatably is supported by a cylinder head. The first intake cam and a second intake cam are disposed on and engaged with the first camshaft for common rotation. The first cam slide member is fixed for common rotation with the first and second intake cams. The first cam slide member has a pin groove disposed on the outer periphery of the first cam slide member. The pin groove includes a first side wall and a second side wall opposite the first side wall. The first actuator has a first and a second pins. The first and second pins are individually extendable into the pin groove of the first cam slide member.
