    Abstract: 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.

    Abstract: A ring seal removal tool may have an elongated body extending from a proximal end to a distal end. The elongated body may have a bottom surface and top surface spaced apart from the bottom surface in a height direction. The ring seal removal tool may also have one of a hook or a prying tip attached to one of the proximal end or the distal end. Further, the ring seal removal tool may have a plurality of cutouts in the elongated body. Each cutout may extend from the top surface of the elongated body towards the bottom surface of the elongated body. Each cutout of the plurality of cutouts may be configured to receive a portion of a ring seal having an outer diameter about equal to a width of the cutout.
