An apparatus and method for installing a piston and connecting rod assembly in a cylinder of an engine block includes a frame, an installation rod and a guide defining a channel complementary to the rod. The frame is disposed about an opening at the bottom of the engine block and the guide is positioned on the frame in alignment with a cylinder. The installation rod is coupled to the connecting rod and the rod and the piston and connecting rod assembly are slid into the cylinder. The installation rod is received within the guide channel and maintains the connecting rod perpendicular to the crankshaft and away from the cylinder wall. As the connecting rod moves toward the crankshaft, the guide and rod move the connecting rod into proper alignment and contact with the crankshaft.

An internal combustion engine includes a crankcase and an upper oil pan. The crankcase includes a plurality of main bearing caps extending between a pair of side walls, with openings in the main bearing caps and in the side walls. The upper oil pan is configured to sealingly engage the crankcase, and includes openings therethrough, which align with the openings in the main bearing caps and the side walls when the upper oil pan engages the crankcase. Fasteners structurally tie the upper oil pan to both the crankcase side walls and the main bearing caps. The engine may further include a lower oil pan defining a sump and attached to the upper oil pan. The upper oil pan preferably includes an oil filter manifold, an oil scraper, and a plurality of oil passages, while also providing a windage tray.

The present invention provides a suspension link assembly for use in interconnecting a suspension member to frame structure in a motor vehicle, and which finds particular application in rear independent suspension systems. The suspension link assembly includes an elongated extension rail and a tie rod assembly. The extension rail is a stamped component defining a generally U-shaped cross-section. The extension rail has a first end adapted to be pivotably connected to the frame structure and a second end defining an open-ended socket. The tie rod assembly includes a housing defining an annular cavity and a shank, and ball joint retained in the housing cavity and adapted for pivotable connection to the suspension member. The shank of the tie rod housing is slidably inserted into the socket of the extension rail. Once the desired length of the suspension link assembly is determined, the shank is rigidly secured in the socket, such as by a welding operation.
