A compression limiter fastener assembly for assembling a first assembly member to a second assembly member has fastener element with a drive head and a shank portion extending from the drive head to a point section. The shank has a non-threaded portion proximate to the drive head and a distal threaded portion positioned at a distal portion of the shank opposite from the drive head. A sleeve element has a tubular section with a bore therethrough sized to surround the threaded end portion and the non-threaded portion of the shank with clearance to allow the shank to be laterally movable in the bore. The sleeve element has at least one radially inwardly extending tab engaging the shank such that the threaded section is axially retained within the confines of the bore namely within the axial extent of the sleeve element until final installation.

A crankcase oil catcher, the crankcase oil catcher comprising one or more surfaces configured to catch dispersed oil in a crankcase and direct the oil along the surfaces of the crankcase oil catcher away from a crankcase casing wall and towards a crank sump.

A modular assembly having a press-fit fastener hole. The press-fit fastener hole may include a plurality of lobe regions and a plurality of contact regions that may be spaced between lobe regions for a press-fit engagement with a fastener. The fastener may have a first diameter and the contact regions collectively may define an imaginary second diameter that is less than or equal to the first diameter.

A cylinder block of an internal combustion engine includes an oil drain hole that opens in a lower surface of the cylinder block. An oil pan is fixed to a lower part of the cylinder block and configured to collect oil. A balancer device is arranged inside the oil pan below a crankshaft. A baffle plate is flat and arranged inside the oil pan between the crankshaft and the balancer device covering the balancer device from above. An oil flow passage extends through the baffle plate in a thickness-wise direction. The oil flow passage is arranged in the baffle plate at a location overlapped with an oil falling path that extends from the oil drain hole to a bottom surface of the oil pan.

In a vehicle oil pan guard including a guard plate mounted on a support member via a mounting portion such that the guard plate is arranged at a position under an oil pan storing a hydraulic oil for protecting the oil pan from an impact from below, a cover plate different from the guard plate is mounted together with the guard plate via the mounting portion on the support member such that the cover plate closes an opening formed near the guard plate toward a road surface.

An oil pan assembly including a first portion having an inner set of openings configured to receive a first set of fasteners to couple the first portion to an engine block and a second portion having an outer set of openings positioned laterally outward relative to the inner set of openings and configured to receive a second set of fasteners to couple the second portion to the first portion and the engine block.

A lubrication system for a machine includes a sump to collect a bulk portion of a fluid lubricant and a pump adapted to circulate the lubricant from the sump through a lubricant line to a lubrication target area of the machine. The lubrication system also includes a dip stick defining a first end outside of the machine, a second end immersed in the bulk portion of lubricant, and a lubricant level indicator between the first end and the second end. The lubrication system further includes an additive fixture coupled to the second end of the dip stick. The additive fixture includes at least one additive material section adapted to dissolve in the lubricant to distribute an additive chemical in lubricant circulating through the machine.

An oil pan assembly for a vehicle engine includes an oil pan having a sectioned base, a sidewall, and a peripheral flange operatively configured to be coupled to an engine block; and a plurality of openings in the oil pan operatively configured to attach the oil plan to an engine block via a plurality of corresponding fasteners.

An oil pan for an engine comprises a containment portion of unitary construction. The containment portion has a circumferential component defining a circumferential extent of the containment portion and comprising a pair of mutually opposing side walls. The containment portion also comprises a base wall extending inwardly from a first portion of the circumferential component and defining a lower extent of the containment portion. The oil pan also comprises an attachment portion comprising an attachment surface at a second portion of the circumferential component; a first plug portion on an interior of a first one of the pair of mutually opposing side walls at a first location; and a second plug portion on an interior of a second one of the pair of mutually opposing side walls at a second location. The first and second plug portions are configured to receive an oil syphon connector and the attachment portion has a rotational symmetry such that the attachment surface is connectable to an engine block in a first orientation and in a second orientation. The first and second plug portions are located such that an oil tube having a fixed location relative to the engine block aligns adjacent the first plug portion on attachment of the attachment portion to the engine block in the first orientation and aligns adjacent the second plug portion on attachment of the attachment portion to the engine block in the second orientation.
