ABSTRACT:
An oil jet nozzle (24) has an extruded body (48) with an integrally formed tab (64). The tab is constructed to be snugly received in an oil groove (32) situated along the bearing seat (34) in the crankshaft journal of the engine block. The groove which receives oil from an oil gallery (42) passes some of the oil through to the nozzle which sprays the oil from two outlets (46) to two adjacent pistons (14) for cooling thereof.
