Abstract: A piston cooling system for an internal combustion engine has a connecting rod assembly for connecting a piston to a crankshaft. The connecting rod assembly may have a connecting rod, a connecting rod bearing, a piston pin bushing, and a piston pin. The connecting rod is mounted on the crankshaft with the connecting rod bearing therebetween. The connecting rod is mounted on the piston pin with the piston pin bushing therebetween. The piston pin is connected to the piston. The connecting rod assembly forms a channel. Lubrication fluid flows through the channel and sprays on the piston during engine operation.

Abstract: A cast oil pan, which is reversible for front and rear sump applications, including an integral suction passage which extends the length of the pan and has outlets at either end, the suction passage including a screened intake seated in the sump area of the pan. Preferably, the bottom surface of the sump area is depressed to create a drain passage beneath the suction passage, the drain passage and bottom surface of the suction passage thereabove having aligned drain ports which are accommodated by a single plug to provide for complete drainage of the pan.
